Biaxial Microincision Cataract Surgery Technique

Study Overview
=================
Brief Summary
-----------------
To analyze and compare visual results, keratometry, SIA and HOAs outcomes of biaxial microincision cataract surgery in elderly population, including diabetic and non-diabetic patients.

Detailed Description
-----------------
Modern trends in cataract surgery is the bimanual MICS technique. MICS significant development for 15 years gives possibility to implant the intraocular lens by 1.4mm incision. This is not only a change in surgery technique, but it is a significant progress in safety and quality post-operative results. Bimanual cataract MICS technique gives the opportunity to reduce width of the corneal incision more than 40% comparing to the standard coaxial cataract surgery by use dedicated MICS IOL's. This allows to perform less traumatic surgery and provides the opportunity for fast visual rehabilitation from the first week after cataract surgery. The possibility of using multifocal and toric intraocular lenses in MICS technique fully meet the requirements of modern refractive intraocular surgery.
