Results of an experimental and clinical study of new hydrophilic intraocular lens implantation for aphakia correction in cataract surgery

Abstract

Purpose. To evaluate results of an experimental and clinical study of new hydrophilic intraocular lens implantation for aphakia correction in cataract surgery. Material and methods. Experimental part was performed using electron scanning microscopy. Surface and angle of the optical edge of the IOL «Aquamarine» were studied. Clinical part included analysis of 500 implantations of Aquamarine IOL with a followup period up to 1 month (group 1), 200 of those implantations had a follow-up period up to one year (group 2). Results. Surface of the IOL had no superficial defects. Optical edge had a rectangular angle over 360°. Area of deviation from the ideal rectangular shape varied between 49.06–175.50 um²at a radius of 40 um and 75.29–264.70 um² at a radius of 60 um. Implantation of Aquamarine hydrophilic lenses made it possible to obtain a high visual acuity of 0.5 or more in 89.6% of cases. Conclusion. A clinical study revealed high uveal and capsule biocompatibility of the Aquamarine IOL, and stable refractive data in the follow up period up to 1 year.
