CLINICAL-RESULTS WITH 3 DIFFERENT KINDS OF SMALL OPTIC PMMA-IOLS

In this prospective study the clinical results using three different s mall optic IOLs are presented. The best results were achieved in those cases with an anterior capsule rim overlapping the entire optic perip hery. In those cases with sulcus fixation, haptic in/out and optic in/ out positions a higher percentage of capsule fibrosis (Soemmering's ri ngs) was documented (sulcus fixation: 100%, haptic in/out position: 75 %, optic in/out position: 65.5%, bag: 7.3%). The fibrosis developed be cause of contact between the anterior and the posterior capsule leaf. These cases also showed decentrations of the intraocular lense (IOL) m ore often (sulcus fixation: 50%, haptic in/out position: 75%, optic in /out position: 34.5%, bag: 31.7%). Only one patient was disturbed by g lare and halo phenomenons. Cellular reactions on the lens surface were moderate in most cases. Differences specific to lens type were found between the three IOLs implanted. The clinical results were comparable to the results of other comprehensive IOL studies. Under certain indi cation small optic IOLs represent an alternative to flexible implants for small incision surgery.
