Abstract
Objective: The authors aim to identify refractometry differences before and after pterygium excision and the approximate period for stabilization of the eye refraction and visual acuity in patients from the Hospital Universitário Bettina Ferro de Souza from April to August 2017, corresponding to the best time for the refractive correction. Methods: The visual acuity, degree and location of the pterygium of 38 patients submitted to pterygium excision in the HUBFS were evaluated before and after 1, 7- and 30-days post-surgery. Data collection was performed through the application of a socio-demographic questionnaire and a form for medical completion in the preoperative and postoperative periods by means of the previous completion of the informed consent form. Results: It was observed that the patients had the following socio-epidemiological profile: mean age of 45.8 ± 13.9 years, 52.6% were women, with a nasal location (84.2%), with a predominance of those with Degrees II and III, only 7.9% were recurrent pterygium; in addition, the pterígios of degrees III and IV had greater variation in their refratometric profile after excision, reaching a maximum average variation of 6.88 diopters of spherical equivalent . Summary: The period less than 30 days after the excision of the pterygium is not enough to prescribe glasses due to a large variation in refractometry in post-surgical patients.
