AI Article Synopsis
- The study aimed to determine how common pseudoexfoliation syndrome (PXF) is in patients set for cataract surgery and its relationship with factors like pupil dilation, lens hardness, intraocular pressure, glaucoma, age, and sex.
- Conducted at Ourense University Hospital in Spain, researchers examined 1,763 eyes from 1,093 patients between January 2013 and July 2013, identifying PXF through specific white deposits on the lens.
- Results showed that 21.6% of eyes had PXF, which was more frequent in older patients, and those with PXF had harder cataracts, higher intraocular pressure, smaller pupils, and a higher prevalence of glaucoma compared to those without PXF
Article Abstract
Purpose: To assess the frequency of pseudoexfoliation syndrome (PXF) in patients scheduled for cataract surgery and to evaluate its association with pupil dilation, lens nucleus hardness, intraocular pressure (IOP), glaucoma, age, and sex.
Setting: Ourense University Hospital, Ourense, Spain.
Design: Cross-sectional study.
Methods: This study evaluated eyes scheduled for cataract surgery between January 2013 and July 2013. Pseudoexfoliation was diagnosed in phakic eyes that showed central and/or peripheral white deposits on the lens surface, pupillary margin, or both. Dilated pupils were evaluated with a portable pupil chart. Nucleus hardness was assessed according to the Lens Opacities Classification System III. Diagnosis of glaucoma was based on International Society Geographical and Epidemiological Ophthalmology criteria.
Results: Of the 1763 eyes (1093 patients) evaluated, 381 (21.6%) were diagnosed with PXF. The frequency of PXF increased with age from 6.0% in people between 50 year and 60 years to 31.66% in those older than 80 years. In PXF eyes, nuclear cataracts were significantly harder than in non-PXF eyes (P < .001). The mean IOP was significantly higher in PXF eyes than in non-PXF eyes (P = .002). The frequency of glaucoma was higher in PXF eyes (17.4%) than in non-PXF eyes (9.4%), with a statistically significant difference (P < .001). In PXF eyes, the pupil was significantly smaller than in non-PXF eyes (P < .001).
Conclusions: The frequency of PXF was high in the study population and increased with age. Eyes with PXF were associated with significantly harder nuclear cataracts, smaller pupils, and glaucoma.

Purpose: To study the outcomes of phacoemulsification in small pupils (≤4 mm) using pupil expansion devices at a tertiary eye care center in South India.
Methods: The study design is prospective, randomized, comparative, and interventional. Mechanical pupil dilatation with iris retractors (group I), B-HEX ring (group II), and Gupta ring (group III) was compared with respect to pupil size achieved (intraoperative), total surgical time, device addition time, complications, endothelial cell loss, and postoperative best corrected visual acuity.
