To date, this is the largest reported case-series comparing Malyugin rings and iris hooks with other pupil expansion techniques. The large pupil (LP) group had a statistically significant greater gain in VA than the SP group (p 0.05) except for a greater rate of iris tears in the Malyugin group (p < 0.05). Of these, 1110 patients (77.8%) had interventions to expand the pupil including 447 (31.3%) with intracameral phenylephrine (IC PE) alone, 194 (13.6%) with iris hooks and 469 (32.9%) with a Malyugin ring. One thousand, four hundred twenty-six patients were identified as having small pupil (SP). A total of 16.7 of the eyes operated on using hypromellose developed a non-reactive semidilated pupil whereas none of the eyes from the control group developed. Many patients are back to their regular activities the day after cataract. Urrets-Zavalia syndrome (UZS) was first described in 1963 as the appearance of a fixed and dilated pupil following penetrating keratoplasty for keratoconus in. While it is normal for pupils to be slightly different size, large or new anisocria.
Outcomes such as visual acuity (VA), intraocular pressure, intraoperative, post-operative complications were recorded and small pupil expansion device outcome. Immediately following cataract surgery, it is, in fact, normal to have blurry vision. Unequal pupil sizes, called anisocoria, is a common vision condition. Retrospective case-series reviewing 20,175 patients’ cataract surgery electronic medical records at Moorfields Eye Clinic in Bedford Hospital NHS Trust from January 2010 to April 2020. To investigate outcomes for small versus large pupils in cataract surgery using different pupil expansion techniques.
