Abstract Details

Purpose:

To evaluate changes in intraocular lens (IOL) position and refraction between a C-loop single piece IOL and a plate haptic IOL after YAG laser capsulotomy.

Setting:

Department of Ophtalmology, Hospital de Braga

Methods:

In a prospective study, anterior chamber depth (ACD) and objective refraction were measured in 83 pseudophakic eyes from 60 patients, before and one month after YAG laser capsulotomy. Patients were divided into two groups according to the IOL desig: Group A (C-loop acrylic hydrophobic single piece AcrySof® SA60AT Alcon Laboratories) and Group B (plate haptic acrylic hydrophilic AT LISA tri 839MP® Carl Zeiss Germany). Lens position was obtained through optical coherence biometry (Biograph WaveLight OB820®, Alcon) and objective refraction (spheric equivalent, sphere, cylinder and axis) was evaluated through autorefractometry (Topcon RM 8900®, Topcon, Japan).

Results:

Differences were found between the lens position of the two groups. The capsulotomy led to a change of ACD in group A from 4.06 ± 0.4 mm to 4.11 ± 0.39 mm (p>0.05) and in group B from 3.98 ± 0,3 mm to 3.84 ± 0.32 mm (p<0.05). Before capsulotomy, the mean spherical equivalent (SE) of group A was -0.11 ± 0.94 D and of group B was -0.03 ± 0.67 D (p>0,05). After capsulotomy, the SE value decreased in both groups: group A to -0.21 ± 0.62 D (p>0,05) and in group B to -0.13 ± 0.50 D (p>0,05).

Conclusions:

According to the design of IOL, it seems that the position of the lens varies after YAG capsulotomy. With plate haptic IOL there is a tendency to a forward movement, and in a C-loop single piece IOL the tendency is to a backward dislocation. These alterations are not associated with significant differences in refraction after capsulotomy.
