Overcoming Biometry Errors Using UV-Light-Adjustable IOL
Purpose
To report on cases of refractive surprises after surgery and the final outcome obtained by utilizing the Light Adjustable Lens.
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
In 15 eyes, final MRSE outcomes after light treatments on a light adjustable IOL are more than twice as accurate than predicted MRSE outcomes utilizing advanced biometry systems. Case reports on the LAL will be presented.
Conclusion
A light adjustable IOL allows surgeons to overcome refractive misses attributed to advanced biometry systems.
