Abstract Details



Purpose:

To describe the procedure for light adjustable lens implantation after laser cataract surgery (LARCS) and present the visual results achieved with LARCS.

Setting:

Ruhr University Eye Hospital, Bochum, Germany

Methods:

LARCS was performed with the Catalys Femtosecond Laser (OptiMedica, Sunnyvale, CA) with a 5.0 mm capsulotomy. Phacoemulsification, aspiration, and irrigation were performed with the Stellaris platform (Bausch+Lomb, Rochester, NY). A capsular measuring ring (Dr. Schmidt, Sankt Augustin, Germany) was implanted followed by implantation of the light-adjustable lens (LAL; Calhoun Vision, Pasadena, CA). The first adjustment was begun 7 days post-operation.

Results:

This study included 7 eyes of 7 patients (mean age 73.6 ±7.6 years, range 63-81, 6 females). Four eyes had non-exudative macular degeneration. The mean axial length in this group was 23.6 ±0.8 mm (21.6-23.5 mm; median 22.5 mm) and mean anterior chamber depth was 3.00 ±0.33 mm (2.52-3.43 mm; median 3.06 mm). Two weeks post surgery and 2 days post-lock-in treatment all eyes achieved an uncorrected distance visual acuity (UDVA) and a corrected distance visual acuity (CDVA) of 20/25 or better. All eyes achieved a spherical refraction within ḟ0.25 D, a cylindrical refraction within ḟ0.5D, and IOL centration. There was a significant reduction in capsular bag diameter by 7 days post-operation.

Conclusions:

Capsulotomy of the exact shape and size allowed perfect centration of the LAL post-LARCS. Rapid post-operative refractive stabilization led to earlier adjustments and lock-in procedures and quick visual recovery lowered the burden of wearing UV-light protecting spectacles.
