ABSTRACT
ABSTRACT

Purpose:

To assess the frequency of corneal astigmatism before cataract surgery in a Brazilian sample.

Methods:

This clinic-based cross-sectional study was conducted at the Bonsucesso Federal Hospital, Rio de Janeiro, Brazil. Charts of patients who underwent cataract surgery over a two-year period were retrospectively reviewed, and preoperative keratometric measurements were collected and analyzed.

Results:

A total of 1707 eyes of 1045 patients were enrolled. The corneal astigmatism was less than 1.0 D in 971 eyes (56.9%), 1.0-1.99 D in 496 eyes (29.1%), 2.0-2.99 D in 157 eyes (9.2%), and more than 3.0 D in 83 eyes (4.9%). The mean corneal astigmatism was 0.92 ± (SD) 0.96 D (range 0 - 10.25 D).

Conclusion:

Over 40% of the patients undergoing cataract surgery enrolled in this study had more than 1.0 D of corneal astigmatism and may benefit from the use of toric intraocular lenses. These data can be useful for planning to make this technology available for patients.
RESUMO
RESUMO

Objetivo:

Avaliar a prevalência do astigmatismo corneano antes da cirurgia de catarata em pacientes brasileiros.

Métodos:

Este estudo transversal de base clínica foi realizado no Hospital Federal de Bonsucesso, Rio de Janeiro, Brasil. Os prontuários de pacientes submetidos à cirurgia de catarata durante um período de dois anos foram revisados retrospectivamente, e as medidas ceratométricas pré-operatórias foram coletadas e analisadas.

Resultados:

Um total de 1.707 olhos de 1045 pacientes foram incluídos. O astigmatismo corneano foi menor que 1,0 D em 971 olhos (56,9%), 1,0-1,99 D em 496 olhos (29,1%), 2,0-2,99 D em 157 olhos (9,2%) e mais de 3,0 D em 83 olhos (4,9%). A média do astigmatismo corneano foi de 0,92 ± (SD) 0,96 D (intervalo 0-10,25 D).

Conclusão:

Mais de 40% dos pacientes estudados submetidos à cirurgia de catarata incluídos neste estudo tinham mais de 1,0 D de astigmatismo corneano e podem se beneficiar do uso de lentes intraoculares tóricas. Esses dados podem ser úteis no planejar a disponibilização dessa tecnologia para os pacientes.
