Multicenter Evaluation of Patients Bilaterally Implanted With Clear Aspheric Toric 1-Piece IOL
Purpose
To evaluate the efficacy, stability, predictability, and patient-reported outcomes following bilateral implantation of a clear aspheric toric 1-piece intraocular lens.
Methods
Prospective, multicenter, open label, clinical evaluation of 100 patients bilaterally implanted with an aspheric toric 1-piece IOL. Binocular uncorrected distance visual acuity (UDVA), manifest refraction, and IOL rotational stability were assessed at 1-month and 3-months postoperatively. A patient questionnaire on spectacle independence, visual disturbances, and satisfaction with vision at baseline, 1-month, and 3-months postoperatively was conducted.
Results
This preliminary analysis reports data from 30/100 patients. At 3-months post-implant, the binocular UCVA was 20/40 or better in 61% and 20/20 or better in 14% of patients, which represented a significant improvement from baseline (p<0.001). Spherical equivalent was within +/- 0.5D of target in 81% of eyes. IOL alignment was within +/-5 degrees in 75% and within +/-10 degrees in 80% of eyes. Seventy-seven percent of patients never used distance spectacles after surgery. Frequency and severity of glare and haloes significantly reduced from pre- to post-op. Satisfaction with vision was rated extremely satisfied by 89%. Further data analyzes pending.
Conclusion
Bilateral implantation of a clear aspheric toric 1-piece IOL yielded favorable and stable outcomes with high patient satisfaction.
