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.

Keywords: Presbyopia; soft contact lens; patient satisfaction
ÖZET
 Amaç: Bu araştırmanın amacı, günlük ve aylık presbiyopi rehabilitasyonunda kullanılan 2 farklı yumuşak multifokal kontakt lensi (MFKL) görme keskinliği ve hasta memnuniyeti açısından değerlendirmesidir. Gereç ve Yöntemler: Altmış iki hastaya Balafilcon A ve Etafilcon A uygulandı. Görme keskinliği, mesafe için 6 m'de logMAR ve yakın için 30 cm'de Jaeger çizelgesi ile uygun fotopik koşullarda değerlendirildi. Tedavi ve rutin takipte, kontrast duyarlılık [contrast sensitivity (CS)] testleri kaydedildi. Hastalar tarafından yakın, orta ve uzak görüş için ayrı ayrı kontakt lens memnuniyetleri ile ilgili olarak gölgelenme, görsel netlik ve genel görüntü memnuniyeti ile ilgili soruları içeren bir anket dolduruldu. Bunların 0-10 arasında puanlanmasından sonra ortalama hesaplandı. Bulgular: Balafilcon A kullanan katılımcılar için 0,053 (±0,02) ve yakın görüş için Jaeger eşeli ile 1,03 (±0,4); Etafilcon A kullanan katılımcılar için uzak görme keskinliği 0,053 (±0,01) ve yakın görüş için Jaeger eşeli ile 1,23 (±0,45) görme keskinlikleri elde edildi. İki mercek arasında yakın ve uzak görüş açısından önemli bir fark olmazken; CS, her iki mercekte de arttı. Ancak bu artış, gözlüklerde tespit edilen artıştan daha azdı. Yakın, orta ve uzak hasta memnuniyeti tüm lenslerde benzerdi. Sonuç: MFKL uygulanan hastaları tatmin edecek bir görsel rehabilitasyon, lensin uzak veya yakın görme ihtiyacına göre tasarımı dikkate alınarak sağlanabilir.
