Narrative Responses:

Purpose
To investigate astigmatism correction achieved after implantation of a UV-Light Adjustable Lens following cataract surgery.

Methods
Eyes with corneal cylinder 0.75D-2.00D undergoing cataract surgery are implanted with the Light Adjustable Lens (LAL: Calhoun Vision, Pasadena, CA). Adjustment of lens power to correct residual spherical error and astigmatism is done 17-21 days postop, followed by an optional second adjustment, and then two lock-in treatments to freeze the lens power. The refractive goal was emmetropia in all eyes.

Results
Study eyes will be evaluated for cylinder reduction (change in magnitude of cylinder pre- versus post-adjustment, % of eyes with cylinder of less than 0.50D). In addition, one case report will be presented.

Conclusion
We hypothesize that the LAL is effective at reducing astigmatism in cataract patients with corneal astigmatism > 0.50D.
