Refractive Accuracy of Spherocylindrical Correction Using UV-Light-Adjustable Lens
To report on the refractive accuracy of treatments of spherocylindrical error with the light adjustable lens.
Eyes with corneal cylinder 0.75-2.00D undergoing cataract surgery were implanted with the Light Adjustable Lens (LAL: Calhoun Vision). Adjustment of lens power to correct residual spherical error and astigmatism was done 17-21 days post-op, followed by an optional second adjustment, and then two lock-in treatments to secure the lens power. The refractive goal was emmetropia in all eyes.
At one week post lock-in for 30 LAL patients, 100% are within 0.50 D of MRSE, and 90% are within 0.25 D of MRSE.
The clinical results from my site suggest that the LALs adjustments can be customized to reduce residual refractive error.
