OBJECTIVE: To describe the prevalence, location and causes of discontinuous capsulotomy during phacoemulsification cataract surgery. METHODS: Retrospective, consecutive, non-comparative study of 971 cataract surgeries – with discontinuous capsulotomy during surgery – performed from January 2009 to June 2010. RESULTS: it was observed a prevalence of 0.02% and capsule discontinuation occurring 100% of the time during the treatment of the nucleus. In 58.33% of the eyes the implant was done in the capsular bag and in 41.67% in the ciliary sulcus. […]

PURPOSE: To demonstrate the corneal magnification using trypan blue in cataract surgery. METHODS: Eight eyes of eight patients undergoing phacoemulsification with an intraocular lens implantation were enrolled in this study. After staining the anterior capsule with Trypan Blue 0.1% and performing the capsulorhexis, the excised anterior capsule was placed on the corneal surface. By observing and measuring the relationship between the border of the excised anterior capsule and the intracameral capsulorhexis opening, the effect of corneal magnification was clearly demonstrated […]

Case report of a 18-year-old male patient with Alport’s syndrome, who presented with renal failure and hearing loss reporting a progressive loss of vision acuity. Slitlamp examination revealed bilateral anterior lenticonus. The patient underwent pre and post-operative corneal and anterior segment tomography with a rotating Scheimpflug system (Pentacam), integrated whole eye (individual laser beam ray tracing) and corneal surface (Placido) wavefront aberrometry (i-Trace). Phacoemulsification and single piece hydrophobic IOL implantation (Acrysof® SN60AT) was performed uneventfully in both eyes. Pre op […]

OBJETIVO: Demonstrar a magnificação corneana utilizando o azul de tripan na cirurgia de catarata. MÉTODOS: Oito olhos de oito pacientes submetidos à facoemulsificação com implante de lente intraocular foram envolvidos neste estudo. Após corar a cápsula anterior do cristalino com azul de tripan 0,1% e realizar a capsulotomia circular contínua, a cápsula excisada foi colocada sobre a superfície corneana. Após observar e aferir a relação entre a borda da cápsula anterior excisada e a abertura da cápsula intracameral, o efeito […]

PURPOSE: To evaluate and to correlate the PNS (patient nuclear score) and time and energy (power US) in patients priorto and following phacoemulsification with intraocular lens implantation. METHODS: This is a prospective study. Twenty two consecutive patients (22 eyes) that underwent phacoemulsification surgery and intraocular lens implantation were enrolled. Full ophthalmologic clinical assessment including Pentacam (Oculus, Pentacam) measurements were performed in all cases prior to surgery (Pre). Excluison criteria were corneal disease or scars. RESULTS: There are statistically significant difference […]

The iridoschisis is the separation of the brochures of the iris. Rare condition that affects typically both eyes of aged woman. The present study is case report of phacoemulsification in patient with iridoschisis and white cataract. Best corrected visual acuity (BCVA) of the left eye was 0.001. The used technique was stop and chop with the use of four hooks of iris and IOL was a folding three pieces hydrophobic acrylic being introduced inside of the capsular bag. Patient evolved […]

PURPOSE: To evaluate the IOPg (gold standard, Goldmann correlated Intraocular pressure) and IOPcc (corneal compensated Intraocular pressure) in patients prior to and following phacoemulsification with intraocular lens implantation METHODS: This is a prospective study. Thirty six consecutive patients (47 eyes) that underwent phacoemulsification surgery and intraocular lens implantation were enrolled. Full ophthalmologic clinical assessment including Ocular Response Analyzer (ORA, Reichert Ophthalmic Instruments, Buffalo, NY, USA) measurements were performed in all cases prior to surgery (Pre) and at follow-up time points: […]

Purpose: To determine the effect on human aqueous humor cultures of topical gatifloxacin 0.3% applied four times a day three days before phacoemulsification compared to topical gatifloxaxin 0.3% applied and same-day surgery. METHODS: Thirty-seven patients with cataract without other ocular diseases were randomly assigned to Groups A and B before phacoemulsification. Group A received topical gatifloxacin 0.3% same-day surgery and Group B received gatifloxacin 0.3% four times a day three days before phacoemulsification. After the procedure the aqueous humor was […]
