Abstract Details
Purpose:
Placement of intraocular lenses (IOL) at the level of the anterior capsulotomy has several potential advantages including predictable lens positioning, accurate lens centration, avoidance of iris chafing from sulcus IOL implantation, and prevention of negative dysphotopsias. We conducted this study to evaluate the clinical outcomes of a new one-piece, acrylic, capsulotomy-based IOL (CBIOL).
Setting:
Ambulatory Surgical Center, Peregrine Eye and Laser Institute, Makati, Philippines
Methods:
Prospective interventional case series. Fourteen consecutive eyes of 12 patients, with mean age (SD)= 72.5 (12.9) years, underwent laser-assisted cataract surgery and enclavation of a monofocal CBIOL (Femtis, Oculentis, Berlin, Germany) at the laser anterior capsulotomy (5.0 mm diameter) plane. Main outcome measures: preoperative and 1- and 6-month uncorrected (UCDVA) and best-corrected distance visual acuity (BCDVA) and manifest refraction spherical equivalent (MRSE). The patients were queried about negative dysphotopsias. One-way analysis of variance was used to analyze means at the 3 different time points; the t-test was used to analyze 2 means (significance level= 0.05).
Results:
There were significant improvements in visual acuity after CBIOL implantation. The mean (SD) preoperative, 1- and 6-month UCDVA were: 0.1 (0.1), 0.7 (0.3) and 0.8 (0.3) (P < 0.0001). The mean pre-, 1- and 6- month postoperative BCDVA were 0.3 (0.3), 0.8 (0.2) and 0.9 (0.2) (P <0.0001). The mean 1- and 6-month manifest refraction spherical equivalents (MRSE) were unchanged: -0.4 (0.5) and -0.4 (0.6) diopters (P= 1.00; 95CI, -0.429 to 0.429). The mean difference between target and achieved MRSE was -0.49 (0.26) diopters. None of the patients reported negative dysphotopsias postoperatively. There were no adverse events observed.
Conclusions:
A new, monofocal, CBIOL provides good distance vision after implantation with very stable refractive outcomes at 6 months. It is easy and safe to implant and may prevent negative dysphotopsias. Surgeons should determine and apply personalized A-constant to achieve optimal outcomes.
