Abstract Details

Purpose:

The purpose of this study was to analyse corneal multifocality generated by Presbylasik central surgery and assess post-operative results stability for a period up to of three years.

Setting:

University of Alicante, Alicante; Vissum Alicante, Spain

Methods:

This study included 24 eyes of 12 patients divided into two groups; 12 presbyopic myopic and 12 presbyopic hyperopic. All patients were surgically treated with central Presbylasik. Topographic measurements were conducted before the surgery and three-month, one-year and three-years after surgery. Patients’ mean age at the time of surgery was 50. Mean postoperative spherical equivalent refraction was (-0,31 ± 0,74 dioptres D) in the hyperopic group and (-0,50 ± 0,40 D) in the myopic group. With the purpose of objective analysis of corneal multifocality, a computer tool was used based on Fresnel wavefront propagation algorithm calculated from the corneal transmittance

Results:

In the hyperopic group, postoperative corneal depth of focus (DoF) was 1,55±0,45 D. At 3 year postoperatively, corneal DOF variation was 0,08±0,38 D. In the myopic group, , postoperative corneal depth of focus (DoF) was 1,93±0,25 D. At 3 year postoperatively, corneal DOF variation was 0,36±0,22 D.

Conclusions:

Through the purely objective analysis of the cornea’s surface, it was established that the Presbylasik central technique generates an increase in corneal multifocality in the myopic group, and to a lesser extent, in the hyperopic group. Great stability of corneal DoF is observed in both groups, slightly lower in the myopic group.
