Modified transscleral fixation technique for refixation of dislocated intraocular lenses.
OBJECTIVE
To evaluate the results of transscleral fixation of dislocated posterior chamber intraocular lenses (PC IOLs) by externalizing the haptics through a clear corneal incision.


METHODS
Department of Ophthalmology, Rassoul Akram Hospital, Iran University of Medical Sciences, Tehran, Iran.


METHODS
This retrospective interventional case series comprised 21 eyes (21 patients) in which a dislocated posterior chamber IOL was transsclerally refixated using a small superior clear corneal incision for externalization of the haptics. The suture was tied to the externalized haptic, after which the tied haptic was placed back in the anterior chamber and dialed to externalize the second haptic. After the second externalized haptic was tied, the IOL was reimplanted in the ciliary sulcus. The minimum follow-up was 6 months.


RESULTS
The mean follow-up was 42.7 months +/- 21 (SD). The difference between the mean best corrected visual acuity before IOL dislocation (0.34 +/- 0.21 logMAR) and the mean after IOL refixation (0.38 +/- 0.19 logMAR) was not statistically significant (P = .16, t test). During follow-up, the PC IOL remained well centered in all eyes and no tilt or dislocation was observed.


CONCLUSIONS
Scleral fixation of dislocated PC IOLs using temporary haptic externalization through a clear corneal incision minimized the need for complicated intraocular maneuvers, had a low incidence of complications, and provided an easy and effective way to reposition dislocated PC IOLs.
