AI Article Synopsis
- A study evaluated the wavefront aberration profile of a phakic intraocular lens (PIOL) with a strength of -4.5 D among four patients who previously underwent myopic laser refractive surgery.
- Pre-surgery data simulated the effects of PIOL implantation, while post-surgery data helped develop a model of the eyes after LASIK surgery.
- The findings showed that the PIOL did not degrade optical quality compared to post-LASIK conditions, and its optical quality improved as pupil size increased.
Article Abstract
A phakic intraocular lens (PIOL) of - 4.5 D was characterized from its wavefront aberration profile. A preclinical study was conducted using pre- and post-surgery data from four patients that had undergone myopic laser refractive surgery. All these patients would have needed a PIOL of - 4.5 D. Pre-surgery data were used to simulate the effect of a PIOL implantation. Post myopic refractive surgery data were used to calculate the post-LASIK eye model. Modulation transfer function (MTF), point spread function (PSF) and simulation of optotypes vision were obtained and compared. The PIOL did not worsen the optical quality of the eyes evaluated. High order Aberrations were always higher in the post-LASIK eye model. Optics quality trended to be better in PIOL implantation than post-LASIK surgery as pupil size increased.
