[Retinal periphery and diameter of the optic implants in the posterior chamber (5, 6, 7 mm)].
In a preliminary study of 35 patients that had undergone cataract extraction 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 capsulorhexis, and a Posterior Chamber lens. Indirect ophthalmoscopy with scleral depression, and Goldmann lens biomicroscopy were used to visualize the fundus. We found the smaller the optic diameter was, the better 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.
