Title | Microincision cataract surgery with aberration-corrected IOLs |
Abstract Nr. | A2062 |
Purpose | To assess the visual results, contrast sensitivity and optical aberrations in patients that underwent cataract surgery in one eye with implantation of the aspherical Acritec Acrismart 36A through a 1.5 mm incision after bi-manual phako-emulsification. In the other eye patients underwent a conventional phako-emulsification with implantation of the aspherical Pfizer Tecnis Z 9000 lens. |
Methods | In a prospective randomised study, 50 cataract patients underwent implantation with either the Acritec Acrismart 36A lens or the Pharmacia Tecnis Z 9000 lens. Both lenses have aspherical characteristics. At 2 months the BCVA and the post-operative refraction were recorded, the contrast sensitivity in mesopic and photopic conditions was measured and visual function analysis using the ray tracing system (Tracey) was performed. A subjective evaluation by the patient was also done. |
Results | Two months after surgery, the visual acuity was similar for both eyes in both groups. Contrast sensitivity measurements and ray tracing analysis showed no manifest differences. The per-operative complication rate in the patients that underwent bi-manual phako-emulsification was slightly higher during the learning curve but lower once the technique has been mastered. |
Conclusion | Implantation of the Acritec Acrismart 36A and Pharmacia Tecnis Z 9000 lens, both with aspherical characteristics, resulted in identical optical performances. Nevertheless the original 1.5 mm incision can be maintained when implanting the Acritec Acrismart 36A . After a learning curve, bi-manual phako-emulsification is a safe technique. |
