We reported gait speed and sleep quality improved after cataract surgery followed by implantation of yellow colored intra-ocular lens (IOL) previously. In the present study, we implanted clear IOL and followed systemic health parameters for six months after surgery.
The study was conducted on 71 patients (average age 74.1 years) undergoing cataract surgery with the implantation of a clear soft acrylic IOL. Patients were evaluated using the Pittsburgh sleep quality index (PSQI) and the National Eye Institute Visual Function Questionnaire (VFQ-25) before and then 2 and 6 or more months after surgery. Four-meter gait speed was also determined. Metabolic parameters of serum HbA1c, triglyceride, LDL cholesterol and HDL cholesterol were tested.
The results of preoperative and 2 and 6 months after surgery were 66.4±16.5, 79.5±12.6, and 81.0±13.0 for VFQ-25 score, 5.7±3.5, 5.1±3.1, and 4.8±2.9 for PSQI, and 0.90±0.22, 0.91±0.22, and 0.92±0.22 m/sec for gait speed. Significant improvements were noted in VFQ-25 score of all cases and PSQI of poor sleepers (PSQI>5.5) 2 and 6 months after surgery (P < 0.05, paired t-test). Laboratory data did not show significant changes. Comparison of PSQI between studies of clear and yellow colored IOL revealed significant improvement in poor sleepers 6 months after surgery was observed only in the cases implanted with clear IOL.
Cataract surgery with implantation of clear IOL had significant effects on sleep quality and quality of life. Clear IOL might be more beneficial to sleep quality than yellow colored IOL.
