Abstract

Purpose:: To compare the eye’s optical quality in mid-high myopic patients after phakic IOL (Verisyse, AMO) and LASIK refractive surgery.

Methods:: We evaluated the retinal image quality of a group of patients with mid-high myopia (higher than -5D) with a range of ages lower than 40 years, and preoperative best spectacle corrected visual acuity (BSCVA) 20/25 or better, submitted to two different refractive surgery procedures at the IMO center: phakic IOL and LASIK. Each technique was applied over a set of 20 patients and their eye’s optical quality for 4 and 6 mm pupil diameter was measured at the pre and post surgery stage (one day after the intervention), and 1 and 3 months after the surgery. Measurements were performed using a double-pass based clinical instrument (OQAS, Visiometrics, Spain). Only patients with a postoperative uncorrected visual acuity (UCVA) of 20/25 or better were included in the comparison.

Results:: With the IOL procedure a noticeable worsening of the eye’s optical quality is observed at the post surgery stage. However, 1 and 3 months after the surgery the optical quality parameters are very similar to those obtained at the pre surgery stage. With the LASIK technique, even though the worsening of the eye’s optical quality at the post surgery stage is not so remarkable as with IOL, the patients remain with the same optical conditions, and do not present a complete recovery 1 or 3 months after the surgery. For eyes with similar pre surgery optical quality, IOL implantation provides a higher optical quality than LASIK, even in cases with wave-front guided treatments.

Conclusions:: Even though both techniques are highly effective and predictable in order to correct mid-high myopia, they present different performances. Meanwhile the worsening of the results at the post surgery stage is more noticeable with the IOL technique than with LASIK, the whole recovery of the eye’s optical quality with respect to the pre surgery stage is better when using the IOL technique. These results are in good agreement with theoretical predictions using customized modeling.
