Abstract
BACKGROUND: Intraocular lens (IOL) repositioning and IOL exchange are the main methods of surgical treatment of late in-the-bag IOL dislocation.
AIM: To evaluate refraction, induced corneal astigmatism and IOL tilt after surgical treatment of late in-the-bag IOL dislocation by transscleral suture fixation and exchange to iris-claw IOL with retropupillary fixation.
MATERIALS AND METHODS: 78 of patients with late in-the-bag IOL dislocation were included. Transscleral suture IOL fixation was performed in group I (38 eyes), exchange to iris-claw IOL was performed in group II (40 eyes). Refractometry, keratotopography and optical coherence tomography of anterior segment were performed before surgery, 1 week, 1, 3 and 6 months after surgery.
RESULTS: The groups did not differ in subjective and objective refraction. But there was significant variability of data in the group I 3 and 6 months after surgery. There was no difference in corneal astigmatism in both groups during 3 months, but a significant increase was found in group II 6 months after surgery. There was no difference in IOL tilt between groups before surgery. Decrease of IOL tilt in 180 degrees plane was observed after 1 month in group II, while there was no difference in 90 degrees plane between groups.
CONCLUSIONS: Both methods of late in-the-bag IOL dislocation treatment allow to receive good refractive result, but refraction is less predictable after trans-scleral suture IOL fixation. Surgically induced astigmatism is higher in IOL exchange group due to large sclerocorneal tunnel incision. Transscleral suture IOL fixation does not cause clinically significant IOL tilt.
期刊介绍:
This journal aims to offer expert review articles on the most significant recent developments in the field of ophthalmology. By providing clear, insightful, balanced contributions, the journal intends to serve those who diagnose, treat, manage, and prevent ocular conditions and diseases. We accomplish this aim by appointing international authorities to serve as Section Editors in key subject areas across the field. Section Editors select topics for which leading experts contribute comprehensive review articles that emphasize new developments and recently published papers of major importance, highlighted by annotated reference lists. An Editorial Board of more than 20 internationally diverse members reviews the annual table of contents, ensures that topics include emerging research, and suggests topics of special importance to their country/region. Topics covered may include age-related macular degeneration; diabetic retinopathy; dry eye syndrome; glaucoma; pediatric ophthalmology; ocular infections; refractive surgery; and stem cell therapy.
