Abstract

Background: The Implantable Phakic Contact Lens (IPCL) has been established as a substitute for refractive correction as a distinct financial benefit over the Visian Implantable Collamer lens (ICL), with correction of high levels of ametropia up to −30.0 D.

Aim of the Work: To evaluate endothelial changes after implantable Phakic contact lens in moderate and high myopic patients by specular microscope.

Patients and Methods: Twenty eyes of 14 patients were involved in the present interventional prospective clinical study. All eyes were implanted with IPCL V2.0. Corneal endothelium changes using specular microscopy were measured at the preoperative baseline visit, one week, one month, and three months after surgery.

Results: Improvement of visual acuity (VA) from preoperative value (0.26±0.11) to (0.35±0.10) at the last follow-up period, (p<0.001). Spherical equivalent (SE) markedly improved from (-14.83±1.51) preoperatively to (-0.61±0.27) at the last follow-up period (p-value < 0.001). Maximum intraocular pressure (IOP) increases at one week and one month postoperatively but declines by three months postoperatively (p >0.05). Endothelial cell density (ECD) decreased from 3507.20±258.34 preoperatively to 3441.35±261.25 at the end of the follow-up period (p<0.05). Central corneal thickness (CCT) change was insignificant at the last follow-up period (p>0.05). The coefficient of Variation (CV) change was insignificant throughout all visits (p-value>0.05).

Conclusion: IPCL implantation is a safe, reliable, and cosmetically acceptable method for treating moderate to high degrees of myopia when contraindicated corneal refractive surgery.
