Abstract Details

Purpose:

Despite progressive diffusion of microincision, routine cataract surgeries are still performed with 2.75 mm or more incision. We evaluated refractive, topographic and capsular changes after cataract surgery with plate-haptic IOL insertion.

Setting:

Istituto Clinico Humanitas, Milan, Italy

Methods:

Fourty eyes of 40 patients underwent cataract surgery with 2.75 mm clear-corneal incision, phacoemulsification and aspheric, hydrophobic surface plate-haptic IOL insertion. Pre-, one and three months postoperatively we evaluated BSCVA, refraction, and corneal topography. Posterior capsule opacity, graded from 1 to 4, was evaluated by retroillumination.

Results:

Mean initial BSCVA was 0.3 ± 0.1 logMar with -0.30 ± 2.31 D sph, -1.10 ± 0.47 D cyl, mean topographical cyl was -0.60 ± 0.48 D, and mean pupillary topographic K value was 44.20 ± 1.54 D. Three months postoperatively, BSCVA was 0.0 ±0.09 logMar with -0.05 ± 0.76 D sph, -0.86 ± 0.47 D cyl, mean topographical cyl was -0.72 ± 0.44 D, and mean pupillary topographic K value was 44.00 ± 1.55 D. Posterior capsule opacity was 0.42 ± 0.60 at one month and 0.67 ± 0.39 at three months postoperatively.

Conclusions:

Three months after surgery, mean topographic and pupillary topographic K values were substantially unchanged, subjective astigmatism did not change significantly and mild poster capsule opacity did not hinder visual acuity. FINANCIAL INTEREST: NONE
