Abstract

PURPOSE: To evaluate the long-term results of iris-claw phakic intraocular lens (İOL) implantation in high myopic patients.MATERIALS AND METHODS: 68 eyes of 34 myopic patients were included in the study. All patients underwent an iris-claw phakic İOL with an optic part diameter of 6 mm and overall length of 8,5 mm (Artiflex /Veriflex). All surgeries were performed under local anesthesia. During each visit; refraction, visual acuity, intraocular pressure (İOP), endothelial cell changes and complications were evaluated. RESULTS: The mean age of patients was 29.1±7.1 (range 19 to 45 years) years. In 36 of 68 eyes the Artiflex lens was implanted whereas in 32 eyes Veriflex were implanted. The mean follow–up time was 36 months. Before the surgery the patients mean spherical refraction was -11.5±8.73D (range -7.0 to -18.0D), the mean spherical equivalent (SE) was -12.1±2.2D (range -7.5 to -17.5D) and the mean best-corrected visual acuity (BCVA) was logMAR 0.35±0.13. Three years after surgery, the mean spherical refraction was -0.53±0.78D, the mean SE was -1.12±0.79D and BCVA was log MAR 0.22±0.18. The BCVA was maintained in 10 eyes (14.7%) while 57 eyes (83.87%) gained 1 or more lines of snellen BCVA and a loss of 2 lines BCVA occured in one eye (1.47%). Mean corneal endothelial cell loss was 9.86%. During the follow-up visits one eye (1.47%) had IOP elevation, three eyes (4.4%) had decentration, seven eyes (10.2%) had pupil ovalization, and pigmentary dispersion on the anterior surface of the lens and in one eye (1.47%) choroid neovascularization was observed. CONCLUSION: İris supported phakic anterior chamber İOL implantion in high myopic patients provides satisfactory visual outcomes and patient comfort.

Özet

AMAÇ: Yüksek miyopisi olan hastalarda iris kıskaçlı fakik ön kamara lens implantasyonunun uzun dönem sonuçlarını değerlendirmek.GEREÇ-YÖNTEM: Yüksek miyopisi olan 34 hastanın 68 gözü çalışmaya alındı. Tüm hastalara lokal anestezi altında optik çapı 6 mm, tüm çapı 8 mm olan, katlanabilir iris kıskaçlı fakik ön kamara lensi (Artiflex / Veriflex) yerleştirildi. Takiplerde, refraksiyon değerleri, görme keskinliği, göz içi basıncı (GİB), endotel hücre sayısı ve gelişen komplikasyonlar değerlendirildi.BULGULAR: Hastaların yaş ortalaması 29.1 ± 7.1 (19 ile 45 yıl) yıl arasında idi. Toplam 68 gözün 36’sına Artiflex, 32’ sine Veriflex göz içi mercek (GİM) yerleştirildi. Ortalama takip süresi 36 ay idi. Hastaların ameliyat öncesi ortalama sferik refraksiyon değeri -11.5 ± 8.73D (-7.0 ile -18.0D arası), sferik eşdeğeri (SE) -12.1 ± 2.2 D (-7.5 ile -17.5D arası) ve düzeltilmiş en iyi görme keskinliği (DEİGK) ortalaması logMAR 0.35 ± 0.13 idi. Ameliyat sonrası 3.yılda ise hastaların sferik refraksiyon değeri ortalaması -0.53 ± 0.78D, ortalama SE değeri -1.12 ± 0.79D ve DEİGK ortalaması logMAR 0.22 ± 0.18 olarak bulundu. Ameliyat sonrası DEİGK’da 10 hastada (%14.7) değişiklik olmazken, 57 hastada (%83.87) en az bir sıra artış, bir hastada (%1.47) ise iki sıra azalma saptandı. Santral korneal endotel hücre kaybı oranı %9.86 bulundu. Takiplerde bir gözde (%1.47) GİB yükselmesi, üç gözde (%4.4) GİL’de desantralizasyon, yedi gözde (%10.2) pupil ovalizasyonu ve GİM üzerinde pigmentasyon, bir gözde (%1.47) ise koroid neovaskülarizasyonu saptandı.SONUÇ: Yüksek miyopisi olan hastalarda uyguladığımız iris kıskaçlı fakik ön kamara lensi ile refraksiyon, görme keskinliği ve hasta konforu açısından oldukça tatminkar sonuçlar alındı.
