A photoreactive lens implant had good refractive stability over time and improved the visual outcomes of patients, a clinical trial found.
Investigators evaluated clinical and anatomic outcomes of the Light Adjustable Lens (Calhoun Vision). The silicone implant absorbs ultraviolet light, allowing for power adjustment after implantation.
The prospective study included 40 eyes of 40 patients with an average age of 72 years who were diagnosed with visually significant cataracts. After undergoing small-incision phacoemulsification and lens implantation, patients were directed to wear ultraviolet-protective glasses until the lock-in treatment was performed. All patients were compliant.
Mean spherical equivalent refraction improved from 0.58 D before surgery to 0.04 D 4 months after refractive lock-in. Mean sphere improved from 1.02 D to 0.24 D, and mean cylinder improved from 0.88 D to 0.41 D. In addition, corrected distance visual acuity improved by two or more lines in 81% of eyes, the authors reported.
