Astigmatism Correction With Light-Adjustable Lens
Purpose
To present results of astigmatism correction achieved after adjustment of an implanted UV-light adjustable lens following cataract surgery.
Methods
Eyes with corneal cylinder 0.75-2.00D undergoing cataract surgery are implanted with the Light Adjustable Lens (LAL: Calhoun Vision). Adjustment of lens power to correct residual spherical error and astigmatism is done 17-21 days post-op, followed by an optional second adjustment, and then two treatments to lock in the lens power. The goal was to reduce all residual astigmatism to ≤ 0.50D.
Results
The LAL shows good stability within the capsular bag. At one week post lock-in, over 90% of patients have less than or equal to 0.50 D of cylinder.
Conclusion
In patients with preexisting astigmatism, my initial results demonstrate that the LAL is capable of reducing astigmatism.
