Narrative Responses:

Purpose
To compare the pre-adjustment and post-adjustment visual and refractive outcomes in patients receiving a UV-Light Adjustable Lens.

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
Changes in uncorrected visual acuity, cylinder, MRSE, and difference between BSCVA and UCVA will be compared for study eyes pre-adjustment versus post-adjustment.

Conclusion
We hypothesize that the adjustment of the LAL improves visual acuity and reduces residual refractive error.
