İki Farklı Multifokal Kontakt Lensinin Objektif ve Subjektif Değerlendirilmesi: Randomize Klinik Çalışma

Abstract

Objective: The aim of this research is to evaluate 2 different soft multifocal contact lenses (MFCL) that were used in daily and monthly presbyopia rehabilitation in terms of visual acuity and patient satisfaction. Material and Methods: Balafilcon A and Etafilcon A were applied to 62 patients. Visual acuity was evaluated in appropriate photopic conditions with logMAR at 6 m for distance and with Jaeger chart at 30 cm for near. Treatment and routine follow-up letter contrast sensitivity (CS) tests were recorded. A questionnaire was filled by patients regarding their contact lens satisfaction separately for near, intermediate and distance vision that includes questions about ghosting, visual clarity, and overall image satisfaction. The average was calculated after scoring of these between 0-10. Results: Visual acuities were obtained: For the participants who used Balafilcon A is 0.053 (±0.02), and in near vision Jaeger chart 1.03 (±0.4); for the participants who used Etafilcon A is 0.053 (±0.01) in distance visual acuity and in near vision Jaeger chart 1.23 (±0.45). While there was no significant difference in near and distance vision between the 2 lenses, the CS increased in both lenses. However, this increase was lesser than the detected increment in glasses. The near, intermediate and distance patient satisfaction were similar in all lenses. Conclusion: A visual rehabilitation that satisfies MFCL applied patients can be achieved by considering the design of the lens according to the need for distance or near vision.
