Resultados y Complicaciones de Cirúrgia de Catarata por Facoemulsificación: Outcomes and complications of cataract surgery by phacoemulsification

Purpose: To describe outcomes and complications of phacoemulsification cataract surgery with intraocular lens implantation in the San Jose Hospital and explore the association between possible factors with intraoperative complications. Materials and methods: Retrospective case series. We included all the eyes undergoing phacoemulsification cataract surgery between 2010 and 2016. We excluded cases with insufficient records, cases converted to extracapsular cataract extraction by causes different of complications and those who underwent scheduled combined surgery. We described unique intraoperative characteristics of the eye, cataract hardness, intraoperative collaboration of the patient, visual and refractive outcomes and complications during the first postoperative month. The association between unique characteristics of the eye and intraoperative complications was evaluated using the chi-square test considering a p-value of less than 0.05 as statistically significant. Results: We included a total of 2047 eyes. A month postoperatively, 86.8% achieved a best-corrected visual acuity of 20/40 or better and 75.2% achieved spherical equivalent of ±1.00D. Eyes with any particular characteristic presented more intraoperative complications (p=0.01), the same as those with extremely hard cataract (p=0.003) and with deficient collaboration during the surgery (p
