Comparison of Visual and Refractive Results With Implantation of UV-Light-Adjustable IOL Prior to Adjustment Versus Post Lock-in
To compare the pre-adjustment and post-lock-in visual and refractive outcomes in subjects receiving a UV-light adjustable lens.
Eyes with corneal cylinder 0.75-2.00D undergoing cataract surgery are implanted with the Light Adjustable Lens (LAL: Calhoun Vision, Pasadena, CA USA). 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.
Data results for one week post lock-in: more than 90% of my LAL patients have cylinder within 0.50 D and MRSE within 0.50 D, and 80% more than 75% have visual acuity of 20/20 or better.
My data shows that the adjustment of the LAL improves visual acuity and reduces residual refractive error.
