RETINAL PERIPHERY AND DIAMETER OF POSTERI OR CHAMBER LENS OPTIC 5, 6,7 MM)

In a preliminary study of 35 patients that had undergone cataract extr action surgery, we compared the visualization of the retinal periphery according to the intraocular lens optic diameter (5, 6, and 7 mm). In all cases, we performed extra-capsular cataract extractions, with a c apsulorhexis, and a Posterior Chamber lens. Indirect ophthalmoscopy wi th scleral depression, and Goldmann lens biomicroscopy were used to vi sualize the fundus. We found the smaller the optic diameter was, the b etter the visualization of the peripheral retina was. Indeed there was a wider space between the optic ridge of the lens and the iris. There was also a better transparency of the peripheral capsular bag.
