Abstract

Aim: To evaluate the visual outcome of single piece yellow tinted hydrophobic acrylic intraocular lens (IOL) following phacoemulsification.
Materials and Methods: A single center, hospital based, prospective, observational study. Eligible patients with significant cataract, underwent phacoemulsification with implantation of single piece yellow tinted hydrophobic acrylic IOL. Patients followed up for 6 months. Pre and post-operative assessment of UDVA, CDVA was done and documented in LogMAR values. Contrast sensitivity by Pelli-Robson chart, refraction by Auto refractometer was evaluated pre and post operatively. Post-operative evaluation of glistening and PCO done by slit lamp examination. Glare evaluated by pen-torch contrast sensitivity method. Adverse events documented on regular follow-up.
Results: 132 patients were enrolled in the study. Majority of the subjects (97.7%) achieved expected visual outcome of LogMAR 0.0-0.2 on final follow-up day. Statistically significant improvement in contrast sensitivity noted in 99.2% of our patients. The mean refractive spherical equivalent at 180 days was 0.10±0.81. The incidence of glistening was 3.8% at 180 days follow up. Glare was present in 4.6% subjects on first operative day, 3% on 3rd and decreased to 0.8% on 7th postoperative day. None of our patients complained of glare after 1 month. The incidence of PCO and adverse events was 0.8% and 15.2% respectively, on last postoperative follow-up.
Conclusion: Implantation of single piece yellow tinted hydrophobic acrylic IOL provides expected visual outcome, refractive stability, enhances contrast sensitivity with minimal glistening, glare and adverse events. The square edge design of the hydrophobic lens reduces incidence of posterior capsular opacification.
