Abstract

Objective: The
aim of this study is to determine preoperative ocular risk factors and
indications for secondary intraocular lens (IOL) implantation surgery and to
compare the visual outcomes of this procedure.

Material and Methods: Nineteen
patients who underwent secondary IOL implantation between January 2018 and
February 2019 at Kırıkkale University Faculty of Medicine were included in the
study. Preoperative causes of secondary IOL implantation, additional ocular
pathologies such as pseudoexfoliation (PEX), uveitis, trauma, systemic
syndromes, best corrected visual acuity (BCVA) before and after surgery,
surgical procedures and possible postoperative complications were noted
separately.

Results: Nineteen
eyes of 19 patients were included in this study. Eleven (57.9%) of the patients
were female and 8 (42.1%) were male. The mean age of all patients was 69.16 ±
6.92 (59-80) years. When the patients were evaluated preoperatively, the most
common cause was surgical aphakia secondary to intraoperative complications due
to primary surgery in 11 patients (52.6%). The second most common cause was IOL
subluxation in 6 patients. IOL implantation with iris or scleral fixation was
performed in patients who did not have sulcus support and the other IOLs were
inserted to the sulcus. Preoperative mean BCVA was 0.223 ± 0.187, and
postoperative mean BCVA was 0.702 ± 0.209. The difference between preoperative
and postoperative mean BCVA was statistically significant (p <0.001).

Conclusion: IOL
implantation in the sulcus is easier and the complication rate is lower than
the iris and scleral fixation IOL implantation methods. The results of iris
fixation or scleral fixation in cases without sulcus support are also
promising.

SEKONDER GÖZ İÇİ LENS İMPLANTASYONU NEDENLERİ VE CERRAHİ SONUÇLARIMIZ

Abstract

Amaç: Sekonder göz içi
lens (GİL) implantasyonu yapılan hastalarda, preoperatif oküler risk faktörlerini ve ikincil GİL cerrahisi
endikasyonlarını belirlemek ve bu işlemin görsel sonuçlarını karşılaştırmak
amacıyla yapılacaktır.

Gereç ve
Yöntemler: Kırıkkale Üniversitesi Tıp Fakültesi’nde, Ocak 2018 ve Şubat
2019 tarihleri arasında sekonder GİL implantasyonu yapılan ve postoperatif en
az 3 ay takibi olan 19 hasta çalışmaya dâhil edildi. Ameliyat öncesinde
hastaların sekonder GİL implantasyonu nedenleri; psödoeksfoliyasyon (PEKS),
üveit gibi ek oküler patolojiler, travma, sistemik sendromlar, ameliyat öncesi
ve sonrası düzeltilmiş en iyi görme keskinlikleri (DEGK), uygulanan cerrahi
yöntem ve olası postoperatif komplikasyonlar ayrı ayrı not edildi.

Bulgular: Çalışmaya 19
hastanın 19 gözü dahil edildi. Hastaların 11 (%57.9)’i kadın, 8 (%42.1)’i
erkekti. Tüm hastaların yaş ortalaması 69.16±6.92 (59-80) idi. Hastalar
operasyon öncesi değerlendirildiğinde, en sık neden, primer cerrahi sonrası
intraoperatif komplikasyonlara sekonder gelişen cerrahi afaki idi (%52.6,
n=11). İkinci en sık neden ise 6 hastada görülen GİL subluksasyonu idi. Sulkus
desteği olan hastalara sulkus yerleşimli GİL diğer hastalara ise, iris ya da
skleral fiksasyonlu GİL implantasyonu yapıldı. Hastaların cerrahi öncesi DEGK
0.223±0.187 iken cerrahi sonrası DEGK 0.702±0.209 idi. Ameliyat öncesi ve
sonrası görme düzeyleri değerlendirildiğinde aradaki fark istatistiksel olarak
ileri düzeyde anlamlıydı (p <0.001).

Sonuç: Sulkus
yerleşimli GİL implantasyonu, iris ve skleral fiksasyonlu GİL implantasyonu
yöntemlerine göre daha kolay ve komplikasyon oranı daha düşük bir yöntemdir.
Sulkus desteğinin olmadığı durumlarda iris fiksasyonu ya da skleral fiksasyon
yönteminin sonuçları da yüz güldürücüdür.
