Abstract

This study aimed to identify the type of cataract opacity associated with subjective sleep quality for cataract patients. A total of 180 consecutive patients (average age 74.2 years) underwent cataract surgery with implantation of an ultraviolet-blocking or blue light-blocking intraocular lens. The participants' subjective sleep quality was evaluated using the Pittsburgh sleep quality index (PSQI) before and at 2 months after surgery. Patients were divided into two groups for analysis: normal sleepers (preoperative PSQI ≤5) and poor sleepers (preoperative PSQI ≥6). The preoperative and postoperative PSQI scores were 2.8 ± 1.5 and 3.2 ± 2.0, respectively, for normal sleepers (n = 99), and 8.5 ± 2.9 and 7.4 ± 3.3, respectively, for poor sleepers (n = 81). The improvement in PSQI was significant in poor sleepers (p < 0.0001, Wilcoxon's test) with measured values of 0.22 ± 0.96 hours extension in sleep duration and 0.16 ± 0.62 hours shortening in sleep latency. Patients with posterior subcapsular cataract (PSC) and nuclear opacity showed the greatest improvement in PSQI score, with regression analysis identifying PSC as having a significant effect on improvement in PSQI. Significant correlations were found between the subjective sleep and cataract opacity in cataract patients. Ophthalmic personnel should therefore be aware that cataract patients with PSC have a greater potential for disability and predictable benefits from surgery in vision and subjective sleep.
