Purpose: To study the association between tear film hyperosmolarity and ocular light scatter in a cataract surgery population.
Patients And Methods: Contiguous, 20-second objective scatter index (OSI) scans were recorded in hyperosmolar (≥320 mOsm/L) and normal subjects (<308 mOsm/L) with cataract nuclear opacity ≥3. OSI was measured at screening, baseline and 90 days following surgery.
Article Synopsis
- The study aimed to assess the effectiveness and quality of new intraocular lenses (IOLs) designed for presbyopia correction in patients undergoing cataract surgery.
- A total of 60 eyes from 30 patients were implanted with two types of IOLs (Art40 and Art70) and were evaluated for visual acuity and patient-reported outcomes related to vision quality and spectacle dependence.
- Results showed that most patients achieved excellent vision without glasses, with significant depth of focus and minimal reports of visual disturbances such as glare or halos.
Cataracts increase the amount of scattered light in the crystalline lens producing low-contrast retinal images and causing vision impairment. The Optical Memory Effect is a wave correlation of coherent fields, which can enable imaging through scattering media. In this work, we characterize the scattering properties of excised human crystalline lenses by measuring their optical memory effect and other objective scattering parameters, finding the relationship between them.
