The visual performance with the yellow-pigmented IOLs is similar to nonpigmented IOLs under non-ideal conditions.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Purpose: To compare two groups of patients who underwent implantation of blue filtering-yellow-pigmented intraocular lens (IOL) (Alcon AcrySof SN60AT-Natural) and nonpigmented IOL (Alcon AcrySof SA60AT) in terms of: Color perception under mesopic and photopic conditions and contrast sensitivity under mesopic conditions.
📊
Key Findings & Data:Materials and Methods: Pseuodophakic patients with a visual acuity better than +0.1 LogMAR and successful color vision test with Ishihara plates in the post-operative 3rd month were included in this study: 16 eyes of 15 patients (8 male, 7 female) with yellow-pigmented IOL and 8 eyes of 8 patients(4 male, 4 female) with non-pigmented IOL were tested.
💡
Conclusion & Impact:The visual performance with the yellow-pigmented IOLs is similar to nonpigmented IOLs under non-ideal conditions.

Abstract

Purpose: To compare two groups of patients who underwent implantation of blue filtering-yellow-pigmented intraocular lens (IOL) (Alcon AcrySof SN60AT-Natural) and nonpigmented IOL (Alcon AcrySof SA60AT) in terms of: Color perception under mesopic and photopic conditions and contrast sensitivity under mesopic conditions. Materials and Methods: Pseuodophakic patients with a visual acuity better than +0.1 LogMAR and successful color vision test with Ishihara plates in the post-operative 3rd month were included in this study: 16 eyes of 15 patients (8 male, 7 female) with yellow-pigmented IOL and 8 eyes of 8 patients(4 male, 4 female) with non-pigmented IOL were tested. Mesopic (2.4-3.1 cd/m2) and photopic (82-86 cd/ m2) conditions were standardized and patients were tested with Farnsworth-Munsell (FM) 100-Hue test under these conditions. Tri-Va contrast sensitivity test was performed under mesopic conditions. Results: The contrast sensitivity results of both groups were similar. The error scores and the square root of the error scores of FM-100 Hue tests were lower in patients with yellow-pigmented IOLs. However these differences were not statistically significant. Conclusion: The patients with yellow-pigmented IOLs have a similar contrast sensitivity performance compare to patients with non-pigmented IOLs, under mesopic conditions. The color vision performance of patients with yellow-pigmented IOLs is as good as patients with non-pigmented IOLs, both under mesopic and photopic conditions. The visual performance with the yellow-pigmented IOLs is similar to nonpigmented IOLs under non-ideal conditions.

Özet

Amaç: Mavi ışığı geçirmeyen sarı pigmentli göz içi lens (Alcon AcrySof SN60AT-Natural GİL) ve pigmentsiz GİL (Alcon AcrySof SA60AT) yerleştirilen psödofak hastaların fotopik ve mezopik koşullarda renk algılamasının ve mezopik koşullarda kontrast duyarlılığının karşılaştırılması. Gereç ve Yöntem: İshihara renk testinde başarılı olan ve Log- MAR ile görme keskinliği +0.1’in üzerinde olan psödofak hastalar çalışma kapsamına alındı. Çalışmaya sarı pigmentli GİL takılan 8’i erkek 7’si bayan 15 hastanın 16 gözü ile, pigmentsiz GİL takılan 3’ü erkek 5’i bayan 8 hastanın 8 gözü dahil edildi. Cerrahi sonrası 3. aydaki kontrollerinde fotopik (82-86 cd/m2) ve mezopik koşullar (2.4-3.1 cd/m2) standardize edilerek hastalara Farnsworth-Munsell (FM) 100-Hue testi uygulandı. Kontrast duyarlılık ölçümü için mezopik şartlarda Tri-Va testi uygulandı. Bulgular: İki grup olgu arasında kontrast duyarlılık açısından fark bulunamadı. Mavi ışık filtre eden GİL konulan hastalarda FM-100 Hue testi ile elde edilen tüm hata skorları ve bunların karekökleri, pigmentsiz lens konulan hastalara göre daha düşük bulundu ancak bu farklar istatistiksel olarak anlamlı değildi. Sonuç: Mezopik koşullarda sarı pigmentli GİL yerleştirilen olguların kontrast duyarlılıkları pigmentsiz GİL yerleştirilen olgularla benzerdir. Sarı pigmentli GİL yerleştirilen hastalarda mezopik ve fotopik koşullardaki renk algılama performansı pigmentsiz GİL yerleştirilen olgularla aynıdır. Sarı pigmentli GİL yerleştirilen olgular ideal olmayan şartlarda en az pigmentsiz GİL yerleştirilen olgular kadar iyi görsel performans göstermektedir.
