Implantation of bilateral PanOptix trifocal IOL provided satisfactory visual outcomes and quality of vision and life in Chinese patients. Purpose: To report the visual outcomes and quality of vision and life after bilateral implantation of a single-piece trifocal intraocular lens (IOL) in Chinese patients. Setting: Hong Kong Sanatorium & Hospital, Hong Kong, China. Design: Prospective, observational case series. Methods: Patients with bilateral implantation of AcrySof IQ PanOptix multifocal IOL were included. Distance, intermediate (60 cm), and near (40 cm) visual acuities (VAs) and contrast sensitivity (CS), defocus curve, preoperative higher-order aberration (HOA), dysphotopsia (0 to 5), satisfaction (1 to 5), spectacle independence, and quality of life were evaluated. The association between preoperative HOA and postoperative halos was also assessed. Results: 54 eyes of 27 patients were included. The mean binocular distance, intermediate, and near uncorrected VA was −0.05 ± 0.06 (20/18), 0.06 ± 0.10 (20/23), and 0.04 ± 0.05 (20/22), respectively. No eyes lost more than 1 line of vision. Binocular CS was comparable with the monocular population norm of older adults. The defocus curve demonstrated that the binocular VA of 20/25 or better was achieved at a power of −3.00 to +0.50 diopters. The mean scores for halos, glare, and starbursts were 2.4 ± 1.4, 0.2 ± 0.8, and 1.4 ± 1.4 (of 5), respectively. The mean satisfaction score was 4.3 ± 0.7 (of 5). All the patients (100%) reported total spectacle independence. The mean vision-targeted composite score of the vision-related quality-of-life questionnaire was 97.2 ± 9.7 (of 100). Preoperative HOA was not associated with postoperative halos. Conclusions: Implantation of the trifocal IOL provided satisfactory visual outcomes and quality of vision and life, which resulted in a high rate of spectacle independence. [ABSTRACT FROM AUTHOR]

Purpose To compare the refractive and visual outcomes between 2 ablation centration points, 80% and 100% from the pupil center toward the coaxially sighted corneal light reflex. Setting Hong Kong Sanatorium and Hospital, Hong Kong, China. Design Retrospective comparative study. Methods All eyes had myopic laser in situ keratomileusis with the ablation 80% or 100% from the pupil center toward the coaxially sighted corneal light reflex. Three months postoperatively, the refractive and visual outcomes were compared between groups. Subgroup analysis was also performed for the large-angle κ and small-angle κ groups. Results There were no differences in the preoperative variables between groups. Three months postoperatively, the sphere was significantly more hyperopic in the 80% group than in the 100% group (0.19 diopter [D] versus 0.09 D) ( P = .009) and the cylinder was significantly lower in the 80% group (0.25 D versus 0.33 D) ( P = .011). More eyes achieved zero astigmatism in the 80% group than in the 100% group (43.9% versus 34.2%), and fewer eyes had astigmatism greater than 0.75 D in the 80% group (0.9% versus 6.1%) ( P = .039). The error from the target refraction indicated that the 80% group tended to have significantly less undercorrection ( P = .045). There were no significant differences in the other outcomes. Subgroup analysis did not show significant findings for the large-angle κ. Conclusions Both 80% centration and 100% centration were safe and effective. Compared with the 100% group, the 80% group had less astigmatism and less undercorrection.

Purpose: To report the early experience and complications during cataract surgery with a noncontact femtosecond laser system. Setting: Hong Kong Sanatorium and Hospital, Hong Kong Special Administrative Region, China. Design: Retrospective case series. Methods: All patients had anterior capsulotomy or combined anterior capsulotomy and lens fragmentation using a noncontact femtosecond laser system (Lensar) before phacoemulsification. Chart and video reviews were performed retrospectively to determine the intraoperative complication rate. Risk factors associated with the complications were also analyzed. Results: One hundred seventy eyes were included. Free-floating capsule buttons were found in 151 eyes (88.8%). No suction break occurred in any case. Radial anterior capsule tears occurred in 9 eyes (5.3%); they did not extend to the equator or posterior capsule. One eye (0.6%) had a posterior capsule tear. No capsular block syndrome developed, and no nuclei were dropped during irrigation/aspiration (I/A). Anterior capsule tags and miosis occurred in 4 eyes (2.4%) and 17 eyes (10.0%), respectively. Different severities of subconjunctival hemorrhages developed in 71 (43.8%) of 162 eyes after the laser procedure. The mean surgical time from the beginning to the end of suction was 6.72 minutes ± 4.57 (SD) (range 2 to 28 minutes). Conclusions: Cataract surgery with the noncontact femtosecond laser system was safe. No eye lost vision because of complications. Caution should be taken during phacoemulsification and I/A to avoid radial anterior capsule tears and posterior capsule tears.
