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 […]

PURPOSE: To assess intraocular pressure (IOP) before and after 1 day, 3 days, 1 week, 1 month, 3 months, 6 months and 1 year in normal eyes submitted to a phacoemulsification. METHODS: Intraocular pressure retrospective analyses (measured by Goldmann applanation tonometer) of 221 normal eyes of 133 patients submitted to an uneventful phacoemulsification. The IOP was evaluated before and after phacoemulsification ( 1day, 3 days, 1 week, 1 month, 3 months, 6 months and 1 year), and these values were […]

OBJECTIVE: Accurate intraocular lens power calculation may be a challenging issue in eyes with previous corneal refractive surgery. METHODS: The authors present a series of 8 eyes (4 previously submitted to hyperopic laser in situ keratomileusis and 4 to radial keratectomy) submitted to phacoemulsification and implantation of pseudoaccommodating bifocal intraocular lens. Double-K SRK/T formula has been used. RESULTS: Acceptable refractive visual outcomes have been achieved. CONCLUSION: Pseudoaccommodating bifocal intraocular lenses can be safely implanted in patients with previous corneal refractive […]

PURPOSE: To evaluate the complication’s rate of cataract surgery performed by ophthalmology residents (second and third-year) and experienced surgeons at a public teaching hospital. METHODS: A retrospective chart review of all patients who had cataract surgery between March (begin of the technique practice) and November (end of the technique practice) was conducted. RESULTS: In 481 cataracts surgeries, 194 (40%) was performed by third-year residents, 165 (34%) by second-year residents and 116 (26%) by experienced surgeons. The most frequent complication in […]

OBJETIVO: O cálculo preciso do poder da lente intraocular em olhos com cirurgia refrativa prévia é, por vezes, desafiador. MÉTODOS: Os autores apresentam uma série de casos totalizando 8 olhos (4 previamente submetidos a “laser in situ keratomileusis” hipermetrópico e 4 à ceratotomia radial) submetidos à facoemulsificação com implante de lente intraocular pseudoacomodativa bifocal. Foi empregada a fórmula “double-K” SRK/T para esses casos. RESULTADOS: Resultados refracionais satisfatórios foram obtidos. CONCLUSÃO: Lentes intraoculares bifocais pseudoacomodativas podem ser implantadas com boa previsibilidade […]

PURPOSE: the aim of the present study is to compare the intraocular pressure (IOP) and visual acuity (VA) after combined surgery: phacoemulsification with non penetrating deep sclerectomy and phacoemulsification with trabeculectomy. METHODS: this is an observacional and retrospective study by chart review. We selected 148 eyes from 127 patients from Tadeu Cvintal Ophthalmolgy Institute during January 1998 thru January 2007. All patients had primary angle glaucoma and cataract. Seventy seven patients were female, 49 (59%) had phacoemulsification with non penetrating […]

Nós demonstramos a combinação da técnica de monovisão pseudofácica com lente intraocular tórica em pacientes com astigmatismo corneano relevante para reduzir a dependência de óculos após a cirurgia de catarata. Todos os pacientes apresentaram AVsc ³ 20/30 para longe e ³ J2 para perto, sendo que nenhum deles necessitou de correção ótica até o sexto mês pós-operatório.
