Abstract |
PURPOSE To evaluate the role of vitrectomy in transscleral fixation of posterior chamber intraocular lens (IOL) compared to scleral fixation without vitrectomy. METHODS: We reviewed the medical records of 8 eyes which had undergone transscleral fixation with vitrectomy using the three-port-system and 13 eyes which had undergone transscleral fixation only. The postoperative visual acuity, best-corrected visual acuity and changes in astigmatism were compared between the groups. RESULTS: Postoperative uncorrected and best corrected visual acuities were 0.68 and 0.8 in the vitrectomy group and 0.48 and 0.63 in the non-vitrectomy group, respectively. Changes in the amount of astigmatism were significantly less in the vitrectomy group (0.38 diopter) compared to those of the non-vitrectomy group (1.67 diopter). CONCLUSIONS: Transscleral fixation of IOL along with three-port-system vitrectomy resulted in good vision with a smaller degree of astigmatism. Adopting three-port-system vitrectomy seems to have caused the good results, because more complete removal of the lens and capsule remnants and adequate maintenance of IOP with accurate needling and IOL positioning was possible using the system. |
