“…The majority are case reports or small case series, [17][18][19][20] and only 3 studies report the outcomes of posterior chamber toric IOL insertion post-keratoplasty in cohorts of 11 eyes, 21 8 eyes, 22 and 7 eyes 23 with a mean reported follow-up of 1.0 to 3.5 months. Thus, the current study is one of the largest on this topic and has one of the longest follow-ups (O1 year) to date.…”

“…Subsequently, good post-operative visual and refractive outcomes had been consistently reported in several case reports. [8][9][10]12 Alternatively, toric IOL variants like piggyback and iris-fixated toric IOLs have also been reported to correct post-PK astigmatism in pseudophakic patients. 6,20 In our series, there were two subsets of patient groups.…”

“…Nonetheless, there are very limited data available in the literature reporting the outcome of this approach, and most of them are of case reports or small case series. [8][9][10][11] Stewart and McAlister 12 had recently reported good visual outcome following toric IOL implantation with simultaneous cataract surgery in eight patients with post-PK astigmatism and cataract. However, this was conducted as a retrospective study and endothelial cell loss, which represents a major concern in post-PK patient undergoing cataract surgery, was not analyzed.…”

Purpose To report visual and refractive outcomes, and endothelial cell loss following primary and secondary 'piggyback' toric intraocular lens (IOL) implantation in patients with high post-penetrating keratoplasty (PK) astigmatism. Methods Prospective case series. Nine eyes of nine patients with post-PK astigmatism were consecutively recruited for implantation of a customized toric IOL. Six underwent simultaneous phacoemulsification (PE) and three pseudophakic eyes had a secondary 'piggyback' toric IOL implanted in the ciliary sulcus. Mean follow-up time was 17.2 ± 7.7 months. Pre-and post-operative uncorrected (UDVA) and best-corrected (BDVA) distance visual acuities and refractive errors were collected for comparison. Cartesian astigmatic vectors were calculated to identify a change in the magnitude of astigmatism precompared to postoperatively. Pre-and postoperative endothelial cell counts were also collected for analysis. Results UDVA (logMAR) improved from 1.13 ± 0.51 preoperatively to 0.48 ± 0.24 postoperatively (P-value ¼ 0.003). There was no significant change in BDVA (P-value ¼ 0.905) from 0.31 ± 0.27 to 0.26 ± 0.19. Corneal astigmatism preoperatively was 6.57 ± 4.40 diopters (D). Post-operative refractive cylinder was 0.83 ± 1.09 D compared to 3.89 ± 4.01 D preoperatively (P ¼ 0.039). Analysis of astigmatic Cartesian x and y coordinates found a significant reduction postoperatively compared to preoperatively (P ¼ 0.005 and P ¼ 0.002), respectively. Mean endothelial cell loss was 9.9%. Conclusion: Implantation of a customized primary or secondary 'piggyback' toric IOL serves as an effective modality in treating patients with high post-PK astigmatism.

Ö ÖZ ZE ET T AAm ma aç ç: : Yüksek astigmatizmaya sahip kataraktlı gözlerde fakoemülsifikasyon ile birlikte torik göz içi lens (GİL) implantasyonu sonrasında uzak görme keskinliği (GK), astigmatizma değişimi ve göz içi lens stabilitesinin değerlendirilmesi. G Ge er re eç ç v ve e Y Yö ön nt te em ml le er r: : Bu retrospektif çalışmaya korneal astigmatizma değeri 1,00 diyoptrinin (D) üzerinde olup, cerrahi sonrası en az 3 ay takip edilen ve Mayıs 2009 ile Nisan 2011 tarihleri arasında kliniğimizde fakoemülsifikasyon ile birlikte torik GİL implantasyonu uygulanmış olan 16 hastanın 20 gözü dahil edildi. Hastaların cerrahi öncesi ve cerrahi sonrası uzak GK (logMAR), korneal ve refraktif astigmatizma değerleri ölçüldü. Geçirilmiş cerrahi girişimler ve ek oküler hastalıklar kaydedildi. Cerrahi sonrası 1. hafta ile 1. ve 3. aylarda GİL stabilitesi değerlendirildi, hastaların uzak gözlük ihtiyaçları belirlendi. B Bu ul lg gu ul la ar r: : Sekizi (%50) erkek, 8'i (%50) kadın olan hastalarımızın yaş ortalaması 50,40±20,06 (9-81) yıl idi. Cerrahi sonrasında düzeltilmemiş ortanca uzak GK 0,75 (0,22-3,10, logMAR)'dan 0,19 (0-0,52, logMAR) düzeyine; en iyi düzeltilmiş uzak görme keskinliği ortanca değeri ise 0,52 (0,15-3,1, logMAR)'dan 0,10 (0-0,52, logMAR) düzeyine artış gösterdi (sırasıyla p<0,001, p<0,001). Cerrahi öncesi 2,75 (1,25-7,50) D olan ortanca astigmatizma değeri cerrahi sonrasında 0,63 (0-6,00) D'ye geriledi (p<0,001). Cerrahi sonrasında hastaların %50'sinin uzak gözlüğe gereksinim duymadığı saptandı (p=0,021). Cerrahi sonrası 1. ayda torik GİL'te ortalama 3,40±2,11 derece ile kabul edilebilir sınırlarda eksen kayması görüldü. Çalışmaya dahil edilen 3 gözde (2'si keratoplastili) keratokonus nedeniyle 4,00 D'nin üzerinde astigmatizma mevcut idi. S So on nu uç ç: : Astigmatizma ile birlikte kataraktı olan hastalarda torik GİL implantasyonu, uygun teknik ve doğru hesaplama ile yapıldığında görsel sonuçları tatmin edici ve yüz güldürücü bir cerrahi işlemdir. Torik GİL implante edilen hastaların bir kısmında uzak görme için gözlüğe bağımlılık ortadan kalkmakta, kalan kıs-mında ise en azından gözlük numaralarında azalma sağlanmaktadır. and April 2011, and followed up at least 3 months after surgery. Uncorrected and best corrected visual acuities (VA) (logMAR), corneal and refractive astigmatism values were evaluated both preoperative and postoperatively. Previous surgical interventions and coexistent ocular diseases were recorded. Intraocular lens axis was measured on postoperative first week, 1 st and 3 rd months to evaluate rotation, spectacle dependency for distance vision was evaluated. R Re es su ul lt ts s: : The mean age of 8 (50%) male and 8 (50%) female patients was 50.40±20.06 (9-81) years. The uncorrected median VA was developed from 0.75 (0.22-3.10, logMAR) to 0.19 (0-0.52, logMAR) postoperatively (p<0.001). The best corrected median VA was developed from 0.52 (0.15-3.1, logMAR) to 0.10 (0-0.52, logMAR) (p<0.001). The median cylinder power decreased from 2.75 (1.25-7.50) D to 0.63 (0-6.00) D postoperative...
