Abstract
BackgroundThis study aimed to investigate the completion rate, visual performance, and adverse outcomes of femtosecond laser-assisted cataract surgery (FLACS) in Chinese patients.MethodsThis is a prospective, single-arm, multicenter registry study of 19 cataract surgery clinics in China. Chinese patients with cataract who underwent FLACS using the Alcon LenSx® laser system in single eye (n = 1140) or both eyes (n = 201) were enrolled and data were collected between March 2015 and August 2016. Clinical characteristics were recorded before surgery, and on postoperative days 1, 7, and 30. For surgery on both eyes, the second eye was included in the analysis only if it was operated within 30 days after the first eye surgery. The primary outcome was the completion rate of circular anterior capsulotomy. Secondary outcomes for lens fragmentation, corneal incision, and intraocular lens (IOL) implantation included best corrected distance visual acuity (BCDVA) and completion rates. Adverse events (AEs) were recorded.ResultsThe completion rates of circular anterior capsulotomy, lens fragmentation, corneal incision, and IOL implantation were 98.6% (95% CI: 97.8–99.1%), 99.5% (95% CI: 99.1–99.8%), 97.6% (95% CI: 96.7–98.3%), and 100% (95% CI: 99.8–100%), respectively. BCDVA preoperatively and at postoperative day 30 were 1.134 ± 0.831 logMAR and 0.158 ± 0.291 logMAR, respectively. The proportion of eyes with BCDVA of 20/20 or better was 1.6% at baseline and 41.3% at postoperative day 30. AE incidence was 0.32%, with posterior capsule rupture present in 0.19% of eyes.ConclusionFLACS using the LenSx® laser system can achieve satisfactory results in a real-world setting.
Highlights
This study aimed to investigate the completion rate, visual performance, and adverse outcomes of femtosecond laser-assisted cataract surgery (FLACS) in Chinese patients
Baseline characteristics A total of 1435 patients were enrolled in 19 cataract surgery clinics in China, and 1341 patients were treated (Table 1)
The main findings were that completion of a circular capsulotomy, lens fragmentation, intraocular lens (IOL) implantation, and corneal incision were successfully achieved in the vast majority of patients
Summary
This study aimed to investigate the completion rate, visual performance, and adverse outcomes of femtosecond laser-assisted cataract surgery (FLACS) in Chinese patients. Cataract is a major global health problem and the most common underlying cause of reversible blindness worldwide [1, 2]. The management of cataract involves surgery and cataract operations are amongst the most common surgical procedures performed worldwide, cataract surgery rates (CSR) vary widely between developed and developing countries [6]. The conventional technique involves the use of a small incision plus phacoemulsification to remove the lens material followed by the insertion of an intraocular lens (IOL). In this method, the ophthalmic surgeon opens the anterior lens capsule with surgical instruments, a procedure known as continuous curvilinear capsulorhexis (CCC).
