Adjustments of haptics length for tilted intraocular lens after intrascleral fixation.

ABSTRACT:

Purpose

To report the findings and surgical techniques on two cases of severe tilting of an intraocular lens (IOL) that had been implanted with intrascleral fixation and the tilting was detected by anterior segment optical coherence tomography (AS-OCT).

Observations

Two patients underwent flanged intrascleral fixation of an IOL with the double needle technique. AS-OCT showed that the tilt of IOL was 25.3° in Case 1 and was 38.1° in Case 2, and a second surgery was planned to reduce the IOL tilt. Both edges of the flanged haptics were externalized and shortened by 2-3?mm. Then, the haptics edges were inserted intrasclerally. The tilt of the IOLs was reduced to 7.7° and 5.7°, and the myopia-shifted refraction was reduced from -2.75 diopters (D) and -4.50 D to -0.13 D and -0.50 D of the approximate planned refraction in the two cases.

Conclusions and importance

An excessive tilt of an intrasclerally fixed IOL can be corrected by shortening the length of the haptics. AS-OCT was useful in not only detecting the tilted IOL but also in monitoring the degree of tilt after adjustment surgery.
