Abstract Details

Purpose:

To analyze the intraocular lens (IOL) position in reference to the first coaxial Purkjnie reflex and limbus center in patients with different degrees of alpha angle with two different methods of femtosecondlaser-assisted capsulotomy centration.

Setting:

Villa Erbosa Private Hospital GSD, Bologna, Italy

Methods:

Prospective randomized study in patients undergoing femtosecond laser-assisted cataract surgery using the CATALYS Precision Laser system (Abbott Medical Optics). Two groups: group A with an alpha angle <0.4 mm including 20 eyes and group B with an alpha angle >0.4 including 20 eyes. In all cases a randomized capsulotomy of 5.0 mm diameter was performed (pupil or scanned bag centration). In all cases one of three IOL types based on the same platform were implanted (Tecnis One, Sensar 1-piece, Tecnis Symfony, Abbott Medical Optics).First coaxial Purkjnie reflex,IOL geometrical center and limbus center have been analized with i-Trace aberrometer(Tracey Technologies).

Results:

Fourty eyes from 25 patients (age range: 55 to 86 years) were enrolled. The mean distance between the first Purkinje coaxial reflex and the limbus center, the mean distance between the first Purkjnie reflex and the IOL center and the mean distance between the IOL center and the limbus center were calculated. An overlap of the 5-mm anterior capsulotomy and the IOL was found in all cases of both groups, except for one eye with high myopia.

Conclusions:

The final IOL position seems to be more related with the limbus center position than with the location of the capsulotomy. A 5-mm capsulotomy allows a perfect overlap of IOL and capsulotomy, independent of the type of centration, pupil or scanned bag
