Abstract Details


Evaluate the efficiency of scleral contact lenses (SCL) in patients enrolled in the corneal transplantation waiting queue at Hospital de Olhos Aparecida, Goiania, Goias, Brazil


Hospital de Olhos Aparecida (HOA) at Aparecida de Goi�Ã�¢nia, Goi�Ã�¡s, Brazil.


An experimental clinical trial performed at HOA in January, 2017 with 14 eyes.All patients of the hospital�Â�´s waiting for a transplant were included, with exclusion criteria being: cognitive deficit and total corneal opacity. Visual acuity (VA) was evaluated through the Snellen scale before and after the adaptation of the SCL, accounting for the letter gain for each line of sight. The adaptation of the rigid gas permeable Zenlens SCL Sol�Ã�³tica�Â�® was carried out by the same researcher, following the manufacturer's specifications. The variables evaluated: gender, age, corneal transplantation indication�â�€�™s reason and corrected VA before and after adaptation.


The main reason for corneal transplantation indication was keratoconus (57%). The average letter gain of the total sample was 21.71; the lowest being 8.00 letters and the highest 27.20, with a standard deviation of 9.31. There was no statistical significance for the variables gender and age, but there was statistical significance for the indication of transplantation (p <0.05).


It has been found that the greatest benefit of the lenses were in eyes with keratoconus and post infection opacity. Because the SCL were effective, promoting VA improvement in all patients, it is suggested that their test should be tried before the indication of corneal transplantation. However, the handling and acceptance in the continuous use of these lenses were not evaluated in this study.
