To describe the procedure for light adjustable lens implantation after laser cataract surgery (LARCS) and present the visual results achieved with LARCS.
Ruhr University Eye Hospital, Bochum, Germany
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.
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.
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.
