COMPARISON OF INTRAOCULAR LENS FIXATION TECHNIQUES
PERFORMED DURING PENETRATING KERATOPLASTY
In aphakic or pseudophakic eyes with bullous keratopathy it is possible to implant intraocular lenses (IOL) in the
anterior chamber or posterior chamber using transscleral or iris-sutured fixation during penetrating keratoplasty. In this
study, implantation results of three different intraocular lens fixation techniques performed during penetrating
keratoplasty were evaluated prospectively.
IOL implantations were performed in eyes acapsular or lacking partial or full posterior capsule support and having
bullous keratopathy. All cases underwent Implanation during penetrating keratoplasty. 28 eyes were implanted
secondarily while in 4 eyes lOLs were changed, performing three different techiques. Eyes were evaluated regarding
the graft failure, glaucoma, cystoid macular edema (CME) and corneal thickness changes. The follow-up period
averaged 13 months (range, 8 to 24 months). 81.2% of the grafts were remained clear by the end of follow-up period.
The percentage of clear grafts in anterior chamber (Ac) IOL was 75%, 87% in transscleral fixation lOLs and 81.2% in
iris fixation lOLs. Postoperative CME rate was significantly higher in cases with Ac lOLs (p<0.05). Complications
involving retina and releated to lOLs were higher in cases with iris fixation than transscleral fixation.
Early results indicate that the postoperative risks of CME and graft rejection is higher in Aac lOLs implanted
cases than posterior chamber lOLs. Furthermore, transscleral fixation posterior chamber (Pc) lOLs were found to be
more reliable than iris-fixation Pc lOLs.Keywords: Penetrating keratoplasty, A c IOL, Transscleral fixation, Iris-sutured fixation
