Three-point transscleral suture fixation of a foldable three-looped haptics one-piece posterior chamber intraocular lens implantation

A 73-year-old male patient was suffering from aphakia due to ocular trauma. Capsular implantation of a posterior chamber intraocular lens (PCIOL) was impossible in the absence of capsular support. Three-point transscleral suture fixation was used. The technique was performed under retrobulbar anesthesia. A three-looped haptics one-piece foldable PCIOL was suspended in the eye with one haptic at 6 o’clock and tied by a cow-hitch knot, and the haptics at 2 o’clock and 10 o’clock were threaded by another suture. The patient was followed up for 6 months postoperatively, and the postoperative logarithm of the minimum angle of resolution at the final follow-up was 0.3. The intraocular lens remained well positioned and stable. No complications, such as suture loosening, hypotony, chronic inflammation, or retinal detachment, were observed during the postsurgery follow-up period.

Corneal endothelial evaluation after phacoemulsification in eyes with pseudoexfoliation syndrome

Purpose The aim of this study was to evaluate the corneal endothelial cell changes after phacoemulsification in patients with age-related cataract and pseudoexfoliation (PEX) syndrome compared with control patients having age-related cataract using specular microscopy.Patients and methods In this prospective interventional case–control study, 20 eyes with cataract and PEX and 20 control eyes with cataract without PEX were subjected to phacoemulsification and posterior chamber foldable intraocular lens implantation at Minia University Hospital and Genaidy Eye Center, Minia, Egypt, between March 2019 and December 2020. Specular microscopy was done preoperatively and at 3 and 6 months postoperatively. The endothelial cell density (ECD), coefficient of variation, hexagonality (HEX%), pleomorphism, and corneal thickness were evaluated and compared between PEX and control eyes.Results The median best-corrected visual acuity improved significantly from a preoperative value of 0.3 in both groups to 0.5 and 0.6 in PEX and control groups, respectively, at 3 and 6 months postoperatively (P<0.001). In patients with PEX, the preoperative median ECD significantly decreased from 2790.5 cells/mm2 to 2387 at 3 months (P<0.001) and to 2380 cells/mm2 at 6 months (P<0.001). In the control group, the preoperative median ECD significantly decreased from 2599 to 2364 cells/mm2 at 3 months (P<0.001) and to 2353 cells/mm2 at 6 months (P<0.001). There was a statistically insignificant difference between the two groups regarding the preoperative and third and sixth postoperative month ECD (P=0.499, 0.850, and 0.860, respectively). The median of HEX% decreased significantly in the PEX eyes from a preoperative value of 45.5 to 39% at 3 months (P<0.001) and to 38% at 6 months (P<0.001). In the control eyes, the HEX% decreased significantly from a preoperative value of 42 to 38.5% at 3 months (P=0.009) and to 37% at 6 months (P<0.012). There was no statistically significant difference between the preoperative and postoperative values of the coefficient of variation % in either group, with no statistically significant difference between the two groups. In addition, there was no statistically significant difference between the two groups either before or after surgery in the central corneal thickness.Conclusion Although the percentage of reduction in ECD was more in the PEX eyes compared with the control eyes after phacoemulsification, there was no statistically significant difference in most of the studied parameters between the two groups.

P.0328 Adult bipolar disorder and attention deficit/hyperactivity disorder - a common comorbidity?

To explore the cost utility of cataract surgery in patients with stabilized vision-threatening diabetic retinopathy (DR).Department of Ophthalmology, Shanghai General Hospital, Shanghai Jiao Tong University, Shanghai, China.Prospective case series.Patients diagnosed with cataracts combined with stabilized vision-threatening DR had successful phacoemulsification with foldable posterior chamber intraocular lens implantation. The corrected distance visual acuity (CDVA) and utility value obtained using the time tradeoff method at 3-month postoperative intervals were compared with those preoperative values. The cost per quality-adjusted life year gained was calculated using the bootstrap method. Sensitivity analyses were performed to test the robustness of the results.The study comprised 126 patients (153 eyes). All surgeries were successful. The weighted logMAR CDVA changed from 0.82 logMAR ± 0.34 (SD) to 0.58 ± 0.30 logMAR (P < .001). The utility values increased from 0.58 ± 0.14 to 0.72 ± 0.14 (P < .001). The gain in utility values was correlated with the postoperative weighted logMAR CDVA, the change between the postoperative and preoperative weighted logMAR CDVA, performance of bilateral cataract surgery, and duration of DR or diabetic macular edema. The patients gained 1.50 quality-adjusted life years by cataract surgery. The cost per quality-adjusted life year was US $768. This surgery was cost-effective at the threshold of US $22 526 per quality-adjusted life year in China. The cost per quality-adjusted life year varied from US $630 to US $8707 in sensitivity analyses.Cataract surgery was a cost-effective intervention for patients with coexisting, stabilized, vision-threatening DR.

Comparative Study of Postoperative Astigmatism Following Phacoemulsification with Scleral Incision and Posterior Chamber Foldable and Rigid (Nonfoldable) Intraocular Lens Implantation

Purpose: To study and compare the postoperative astigmatism following phacoemulsification with scleral incision and posterior chamber foldable and rigid (nonfoldable) intraocular lens (IOL) implantation. Materials and Methods: It was a hospital-based prospective observational study which included 200 eyes with presenile and senile cataract and were divided into two groups. Group I; included hundred cases with superior scleral incision (3.2 mm) phacoemulsification and foldable posterior chamber IOL (PCIOL) implantation. Group II; included 100 cases with superior scleral incision (5.5 mm) phacoemulsification and rigid (nonfoldable) PCIOL implantation. The data were analyzed by Chi-square test and P &lt; 0.05 was considered statistically significant. The surgically induced astigmatism (SIA) at 6 weeks was compared between the two groups. SIA was calculated by the vector analysis. Results: The mean SIA in Group I was 0.67 ± 0.46 D, whereas in Group II was 1.17 ± 0.44 D. There was statistically significant difference between the two groups P &lt; 0.05. Group II showed higher mean SIA than Group I at 6 weeks. Postoperatively, majority of patients developed against the rule astigmatism, 62% in Group I and 76% in Group II. Conclusion: SIA is less in 3.2 mm incision as compared to 5.5 mm incision with increase in against the rule astigmatism postoperatively.

Misplaced and invisible intraocular lens

Traumatic dislocation of foldable posterior chamber intraocular lens (PCIOL) is very rare and an emergency condition. Again, intra-operative dislocation of foldable PCIOL is very rare. We are reporting a case of inadvertent intraoperative suprachoroidal dislocation of foldable PCIOL without any retinal detachment, irido-dialysis, zonular dialysis, or vitreous loss.

Transfixion of Foldable Intraocular Lens With Polytetrafluoroethylene Suture for Scleral Fixation.

To describe a new scleral fixation technique potentially usable for every acrylic foldable intraocular lens (IOL) available in the market, regardless of whether it is a three-piece, single-piece, or haptic shape. Before surgery, the authors performed the transfixion of the IOL optic in four points with the polytetrafluoroethylene suture under a surgical microscope. Four sclerotomy sites were marked 2 mm from the limbus, and two scleral grooves were created in between. The IOL was introduced into the posterior chamber. The four ends of the needleless polytetrafluoroethylene sutures were externalized through the sclerotomies, tightened for optimum IOL centration, and tied. The exposed sutures were placed within the scleral grooves, and the knots were buried within the sclerotomies. This technique was performed uneventfully in 7 cases. The foldable IOL was stable in all eyes 6 months after surgery, with no signs of IOL subluxation, dislocation, tilt, or suture-related complications, such as erosion or infection. The transfixion of the foldable posterior chamber IOL for stable four-point scleral fixation using a polytetrafluoroethylene suture provides excellent stability and prevents IOL tilt and decentration. This technique can immensely benefit patients requiring secondary foldable posterior chamber IOL implantation in the absence of capsular support. [J Refract Surg. 2021;37(3):180-185.).

Retinal changes after uncomplicated phacoemulsification in diabetic patients

Aim To detect the incidence and progression of diabetic retinopathy (DR) and macular edema following uncomplicated phacoemulsification in cataractous diabetic patient. Patients and methods A prospective randomized interventional study was performed at Al-Zahraa Hospital, during the period from April 2017 to December 2018. Informed written consent was taken from each participant in the study. A total of 60 eyes of 30 cataractous diabetic patients with type II diabetes were classified into two groups: group A included 30 cataractous eyes that underwent uncomplicated phacoemulsification surgeries with posterior chamber foldable intraocular lens implantation, and group B included contralateral nonoperated 30 eyes of the same patients. Results There was a statistically significant increase of mean postoperative central macular thickness (CMT) at 1, 3, and 6 months in comparison with mean preoperative CMT in group A (P&lt;0.05). It was 223.43±15.95 preoperatively. At all duration of follow-up, the mean CMT in group A was more than that in group B, with a statistically significant difference (P&gt;0.05). Conclusion Phacoemulsification surgery most probably does not cause acceleration of DR in patients having no DR or mild DR and no maculopathy preoperatively.

Cataract following electric shock - Case report

Ocular trauma is the under-recognized cause of unilateral blindness particularly in developing nations.The growing demand on generated electricity has also led to increase in electricity related occupational trauma. We report a case of bilateral cataract in a 22 years professional electrician. He survived a high voltage electric shock and sustained burn injury on the right side of his head. Ocular examination revealed typical anterior as well as posterior subcapsular cataract in right eye and visually insignificant early anterior subcapsular vacuoles in the left eye. There was a significant difference in lenticular opacification density in between these two eyes. Uneventful phacoemulsification and foldable posterior chamber intraocular lens implantation was performed in the right eye and the sufferer was rehabilitated with normal best corrected visual acuity. The possibility of ocular complications and importance of ocular screening is emphasized in the survivors of electrical injury. The lenticular opacities can be successfully managed with surgery, however the final visual acuity depends on damage to other vital ocular structures. The clinical features, pathogenic mechanism of these opacities and review of the literatures are discussed.

Steroidal versus non-steroidal eye drops in prevention of cystoid macular edema after cataract extraction in diabetic patients

Background: Cystoid macular edema (CME) is addressed as one of the most important complication responsible for suboptimal visual acuity outcome after cataract surgery. Objective: Comparison between topical steroids versus NSAIDs regarding ability to reduce CME after uneventful cataract surgery of foldable intraocular lens (IOL) implantation in diabetic patients. Patients and methods: In this study, 30 patients underwent phacoemulsification surgery with posterior chamber foldable intraocular lens implantation in Ophthalmology Department, Al-AzharUniversityHospital between December 2017 and November 2018. Patients were randomly categorized into 2 groups. Group 1: Nepafenac eye drops (0.1%) 3 times daily for one month, Group 2: Prednisolone eye drops (1%) 5 times daily for one month. Results: At the end of the follow up, foveal thickness changes in optical coherence tomography (OCT) were found to be slightly less in the no steroidal anti-inflammatory eye drops (NSAIDs) group than in the steroidal group with no significant change in the final visual outcome between the two groups. Conclusion: There was no significant statistical difference between NSAIDs drops and steroids drops in prevention of development of pseudophakic macular edema post cataract surgery.

Evaluation of suturless scleral fixation with posterior chamber foldable intraocular lens implantation.

To assess the sutureless scleral fixation technique for posterior chamber foldable intraocular lens (PCIOL) implantation in aphakic eyes with insufficient or no capsular support. A technique for sutureless intrascleral fixation of the haptics of a standard 3-piece PCIOL was used which ensures sutureless fixation by permanent incarceration of the haptics in a scleral tunnel parallel to the limbus. All patients were evaluated for preoperative status [visual acuity, refractive error, K readings, intraocular pressure (IOP) measurement, slit lamp examination, fundus examination and optical biometry], postoperative status and complications. Ultrasound biomicroscopy (UBM) was done for 10 cases to evaluate optic tilt. The study evaluated 42 eyes of 42 patients. The follow-up period was 6mo. Improvement of best corrected visual acuity (BCVA) one line occurred in 10 cases (23.8%) and loss of one line in 3 cases (7.1%). Intraoperative complications included: haptic kink in 4 cases (9.5%), haptic breakage in 1 case (2.4%), haptic dislocation in 1 case (2.4%), haptic slippage in 3 cases (7.1%), IOL dislocation in 1 case (2.4%) and sclerotomy related bleeding in 1 case (2.4%). Postoperative complications included: transient mild vitreous hemorrhage in 3 cases (7.1%), choroidal detachment in 1 case (2.4%), cystoid macular edema (CME) in 1 case (2.4%), optic capture in 1 case (2.4%), subconjunctival haptic in 2 cases (4.8%), ocular hypotony in 4 cases (9.5%) and ocular hypertension in 1 case (2.4%). There were no cases of retinal detachment or endophthalmitis. UBM showed optic tilt in 3 cases (30%). Fixation of three-piece foldable IOL haptics in scleral tunnel parallel to the limbus-provided axial stability and proper centration of the IOL with minimal or no tilt in most cases and a low complication rate during the follow up period which lasted 6mo.

Clinical observation of a novel technique: transscleral suture fixation of a foldable 3-looped haptics one-piece posterior chamber intraocular lens implantation through scleral pockets with intact conjunctiva

BackgroundTo present the follow-up outcomes of a modified technique of transscleral suture fixation of posterior chamber intraocular lens (PCIOL) in eyes with inadequate capsule support.MethodsA retrospective chart review of 21 patients underwent transscleral suture fixation of a foldable 3-looped haptics one-piece PCIOL implantation through scleral pockets was conducted. Preoperative data and follow-up data for at least 3 months were collected for all patients.ResultsThe mean operative duration was 36.62 ± 10.70 min. The mean pre- and post-operative LogMAR uncorrected distance visual acuity was (1.25 ± 0.50 vs. 0.41 ± 0.22, P < 0.01). The mean pre- and post-operative LogMAR best corrected visual acuity was (0.48 ± 0.25 vs. 0.33 ± 0.24, P < 0.01). The mean proportion of postoperative endothelial cell loss was 11.46 ± 4.78%. The mean postoperative anterior chamber depth was 3.05 ± 0.44 mm. The mean postoperative IOL tilt degree was 2.81 ± 1.41°, and the mean postoperative IOL decentration degree was 0.31 ± 0.13 mm. Four patients with transient corneal edema (19.0%) and three patients with transiently elevated IOP (14.3%) were observed after operation, and such complications were resolved within 1 week. No severe complications were observed.ConclusionsThe modified technique was a feasible method of PCIOL implantation.

Factors influencing myopic shift in children after intraocular lens implantation.

Intraocular lenses have always been a controversial topic in pediatric cataract surgery. In the early 1990s in the post-Soviet states of Eastern Europe, intraocular lenses promised an easier full-time correction and amblyopia treatment. Since 1991, ophthalmologists in Latvia have been implanting intraocular lenses in infants. Amount of the postoperative myopic shift and its influencing factors, analyzed in this article, are important indicators of congenital cataract treatment. A retrospective chart review off 85 children (137 eyes) who underwent foldable posterior chamber intraocular lens implantation at the Clinical University Hospital in Riga, Latvia, from 1 January 2006 until 31 December 2016, was performed. Depending on the age at surgery, patients were divided into six groups: 1-6, 7-12, 13-24, 25-48, 49-84, and 85-216 months. The largest and more variable myopic shift was found in a group of diffuse/total and nuclear cataract with surgery before the age of 6 months. There was a statistically significant correlation between the acquired best-corrected visual acuity and the amount of myopic shift (rs = 0.33; p < 0.001). Comparing the amount of myopic shift in two groups of different intraocular lens implantation target refraction tactics, we did not find statistically significant differences. Comparing the amount of myopic shift and implanted intraocular lens power, a negative, statistically significant correlation was found. The earlier the cataract extraction surgery and intraocular lens implantation is performed, the larger the myopic shift. The morphological type of cataract, best-corrected visual acuity, secondary glaucoma, and intraocular lens power influence the amount of myopic shift.

Simple Technique for Transscleral Fixation of a Foldable Posterior Chamber Intraocular Lens Using a Single Suture

Objective: To explore the simplified technique for transscleral fixation of a foldable posterior chamber intraocular lens (IOLs) in patients with aphakia or inadequate posterior capsule support. Methods: A review was conducted of 18 eyes of eighteen patients with the absence of—or inadequate—capsule support, after the simplified technique of using a foldable posterior chamber intraocular lens (PC IOLs) with stable four-point transscleral fixation, as performed by a skilled surgeon. This technique uses only a single suture and a knot to fix a PC IOL firmly without creating a scleral flap. The mean follow-up time was 18 ± 5.8 months (ranging from 12 to 24 months). Results: All patients exhibited improved visual acuity. No IOL tilt or dislocation or iris capture was observed, and all patients exhibited stable and centered IOL after surgery. No complex complications, such as suture shedding and exposure, corneal endothelial decompensation, persistent uveitis, or retinal detachment and endophthalmitis were observed. Conclusion: The simplified technique proposed here is a reliable, economical, and reproducible method of treating patients with aphakia or inadequate posterior capsule support. It provides excellent IOL stability, reduces surgical duration and complexity, and prevents certain complications.

Unilateral intraocular lens opacification in an otherwise healthy eye

With phacoemulsification with posterior chamber intraocular lens (PCIOL) implant being the standard of care for the past few decades, sufficient time and numbers have been crossed, revealing newer long-term complication related to the procedure. One of such complications being IOL opacification. The case discussed here is a 73-year-old female with no known ocular comorbidities who presented to our center with diminution of vision. The patient had undergone phacoemulsification cataract surgery with implantation of a foldable PCIOL at another center in the year 2006. Examination revealed glistening pearl-like crystalline opacities inside the IOL optic as well as haptic. The patient underwent an uneventful IOL explant with implantation of glued scleral-fixated IOL as a secondary procedure. The explanted lens was sent to another center for analysis who confirmed the presence of crystalline calcium deposits inside the IOL. Such opacities cause severe visual disability and are not amenable to YAG capsulotomy procedures. These cases warrant IOL explant for visual rehabilitation. Although similar cases were reported from Europe and the USA, no similar cases were previously reported from the Indian subcontinent. This is the first such reported case from the Indian subcontinent.

NSAIDs eye drops versus steroidal eye drops after phacoemulsification cataract surgery

Purpose The aim of this study was to evaluate the efficacy NSAID eye drops in comparison with topical steroids following phacoemulsification cataract surgery. Patients and methods This prospective study included 120 patients with senile cataract who were subjected to phacoemulsification cataract extraction with foldable posterior chamber intraocular lens implantation. Postoperatively, patients were assigned to two groups: NSAIDs group and steroids group. All patients were subjected to preoperative and postoperative investigations including autorefractometer, slit-lamp examination, indirect ophthalmoscopy, tonometry, and Nassar color plates. Optical coherence tomography was performed for all patients in the last visit. Results No statistically significant differences were found between both groups in visual acuity (0.20±0.15 in the NSAIDs group and 0.20±0.13 in the steroidal group), corneal edema, or anterior chamber reaction (P>0.05). The mean macular thickness for the steroidal patient group was significantly higher than their counterparts in the NSAIDs group (P Conclusion Both topical NSAIDs and steroids have the same efficacy in preventing inflammation and corneal edema. However, patients subjected to topical steroids were more likely to develop intraocular hypertension and cystoid macular edema.

Efficacy of foldable intraocular lens implantation with suture fixation in the ciliary groove after lensovitrectomy

Objective To evaluate the efficacy of foldable intraocular lens implantation with suture fixation in the ciliary sulcus in aphakic eyes after lensovitrectomy. Methods The clinical data of 22 eyes of 22 aphakic patients after lensovitrectomy were retrospectively analyzed. All patients were treated with implantation of a foldable posterior chamber intraocular lens with suture fixation through corneal micro incision. Patients were followed up from 6 to 30 months. Results During operation intraocular pressure was stability. No eyeball collapsing, choroid detachment, retinal detachment or expulsion of choroid cavity bleeding occurred. In 22 eyes, early postoperative ocular hypotension happened in 5 eyes and intraocular hypertension in 4 eyes, the IOP recovered to normal after drag treatment for 5-7 days. Three eyes with small amount of vitreous hemorrhage were absorbed 7 days after surgery . At the last follow-up time, best corrected visual acuity achieved or exceed preoperative one. The intraocular lens were all in the correct situation. There was no severe complication occurred such as corneal endothelial decompensation, subchoroidal expulsive hemorrhage, suture exposure, endophthalmitis, secondary glaucoma, retinal detachment or eyeball atrophy. Conclusion Foldable intraocular lens implantation with suture fixation in the ciliary sulcus through corneal micro incision for aphakic eyes in patients after lensovitrectomy is a safe and effictive therapy, with small injured and less complications. But the further observation is needed for long-term observation. Key words: Aphakic eye, after lensovitrectomy; Lens, intraocular, posterior chamber; Suture fixation, ciliary suleus

Predictive factors of visual outcome of Malaysian cataract patients: a retrospective study.

To explore the associations between various characteristics of Malaysian cataract patients and their management, and their post-operative visual outcomes, to inform relevant bodies to reduce cataract-related blindness. We conducted a descriptive secondary data analysis of cataract surgery patients in Melaka Hospital, from 2007 to 2014 using the National Eye Database (NED). Patient-related factors (demographic features, systemic and ocular comorbidities) and management-related factors (surgical duration, type of surgery, type of lens) were analysed for their association with visual outcome (acuity). Most patients were Malays (48.23%) and Chinese (38.55%) aged 60-79y (range 0-100y). Hypertension (58.61%) and diabetes (44.89%) were major systemic comorbidities. Glaucoma (6.71%) and diabetic retinopathy (10.12%) were the main ocular comorbidities. Other comorbidities were age-related macular degeneration, pterygium, corneal opacities, macula diseases, vitreous haemorrhage, retinal detachment and pseudoexfoliation (0.70%-1.60%). Preoperatively 7150 (55.03%) eyes presented with poor vision. Uncomplicated phacoemulsification performed quickly with foldable lenses gave good results. Primary care physicians should initiate early detection to prevent late presentation of cataracts causing poor vision and should discuss the risks and benefits of cataract surgery while emphasizing the role of pre-existing comorbidities which may affect the visual outcomes. For good results, phacoemulsification should be done within 30min, without complications, using foldable posterior chamber intraocular lens.

Congenital aniridia with cataract: case series

BackgroundThis study evaluates patients with congenital aniridia and cataract who underwent phacoemulsification, capsular tension ring placement, and foldable intraocular lens implantation.MethodsIn this prospective case series, 10 patients (17 eyes) underwent cataract surgery via a 3.2 mm clear corneal incision. A continuous circular capsulorhexis with <6 mm diameter was employed. A capsular tension ring and HOYA yellow foldable posterior chamber intraocular lens was implanted. All patients wore color contact lenses postoperatively. Paired t test was used to compare visual acuity, intraocular pressure, and corneal endothelial changes before and after surgery.ResultsA single surgeon performed all surgeries. The best-corrected visual acuity improved from value 1.03 ± 0.27LogMAR preoperatively to value 0.78 ± 0.26LogMAR postoperatively (p = 0.000). The photophobic symptoms improved significantly after surgery. The mean corneal endothelial cell density before and after surgery was 3280 ± 473 cells/mm2 and 2669 ± 850 cells/mm2, respectively (p = 0.006). None of the patients developed corneal endothelial decompensation or secondary glaucoma after surgery.ConclusionsTreatment of congenital aniridia and coexistent cataract by phacoemulsification, posterior chamber foldable lens implantation, capsular tension ring placement was safe and effective. Use of colored contact lenses in the postoperative period can reduce photophobic symptoms in this group of patients.Trial registrationChiCTR-OOC-17011638 (retrospectively registered at 12,June,2017)

Pigment dispersion syndrome and pigmentary glaucoma after secondary sulcus transscleral fixation of single-piece foldable posterior chamber intraocular lenses in Chinese aphakic patients

To describe secondary pigment dispersion syndrome (PDS) and pigmentary glaucoma after secondary sulcus transscleral fixation of 1-piece hydrophobic acrylic foldable posterior chamber intraocular lenses (PC IOLs) in aphakic patients in a Chinese population. Department of Ophthalmology, Qingdao Municipal Hospital, Qingdao, China. Retrospective case series. This chart review included eyes that had secondary sulcus transscleral fixation of a 1-piece hydrophobic acrylic foldable PC IOL (Tecnis ZCB00) between March 2011 and March 2014. The patients' demographic data, clinical data, postoperative complications, intervals between initial surgery and the onset of PDS, pigmentary glaucoma occurrences, and findings on slitlamp biomicroscopy, gonioscopy, and ultrasound biomicroscopy (UBM) were recorded. The study comprised 23 consecutive eyes of 21 patients. Seventeen eyes of 16 patients were diagnosed with PDS, and 7 eyes of 6 patients were diagnosed with pigmentary glaucoma. The slitlamp examination and UBM showed that the location between the IOL optic and the posterior surface of the iris was very close. Slitlamp examination of the anterior chamber angle using a gonioscope showed dense pigment deposition on the IOL surfaces. A reverse pupillary block was found in 10 eyes of 9 patients. Other postoperative complications included intraocular hemorrhage, pupillary capture of the IOL optic, IOL tilt, IOL decentration, IOL dislocation, and suture erosion. The 1-piece hydrophobic acrylic foldable PC IOL was not suitable for sulcus transscleral fixation because of a high incidence of PDS and pigmentary glaucoma after surgery in a Chinese population.
