Abstract
To evaluate the results and complications of phacoemulsification surgery in eyes with posterior polar cataracts and compare the techniques of viscodissection and hydrodissection. The medical records of 29 consecutive patients (16 males, 13 females) with posterior polar cataracts (44 eyes) who had undergone cataract surgery were retrospectively reviewed. Patients were divided into two groups according to the technique used; viscodissection was applied to the experimental group (group 1) and hydrodissection to the control group (group 2). The postoperative best corrected visual acuity (BCVA) was 0.19 ± 0.22 logMAR (mean ± standard deviation) (range 0.00-0.70) in group 1 and 0.25 ± 0.18 logMAR (range 0.00-0.70) in group 2. Although the mean postoperative BCVA in group 1 was greater than that in group 2, the difference was not statistically significant (p=0.165). The mean postoperative BCVA was significantly greater than the mean preoperative BCVA in both groups (p=0.00). Intraoperatively, posterior capsular rupture occurred during the removal of the cortex in three eyes (13%) of group 1 patients, with vitreous loss and anterior vitrectomy in one eye only. In group 2, six eyes (28.5%) presented posterior capsular rupture, and anterior vitrectomy was performed because of vitreous loss in three eyes. Although the percentage of posterior capsular rupture was greater in group 2, the difference was not statistically significant (p=0.207). Complications in posterior polar cataract surgeries can be overcome by being careful throughout the surgery and using proper techniques. Viscodissection may be better for avoiding posterior capsular rupture than hydrodissection.
Highlights
Posterior polar cataracts are white, well-demarcated, disc-shaped opacities located on the central posterior capsule and are a form of congenital cataract with autosomal dominant inheritance[1,2].Posterior polar cataract surgery is difficult for surgeons to perform because of the high risk of posterior capsular rupture, which itself stems from the opacity’s adherence to the capsule and the extreme thinness and fragility of the posterior capsule[3-7].In the present study, we evaluated the results and complications of phacoemulsification surgery in eyes with posterior polar cataracts and compared the techniques of viscodissection and hydrodissection
A melhor acuidade visual corrigida pós-operatória foi significativamente melhor do que no pré-operatório, em ambos os grupos (p=0,00)
