To compare the clinical outcomes between sutured transscleral-fixated and intrascleral haptic-fixated posterior chamber intraocular lens (IOL).


Dr Rajendra Prasad Centre for Ophthalmic Sciences, All India Institute of Medical Sciences, New Delhi.


A comparative case series.


Forty eyes of 40 patients were included; 20 in each group. Patients in group 1 underwent sutured transscleral-fixated IOL and those in group 2 underwent intrascleral haptic-fixated IOL augmented by fibrin glue. Parameters evaluated were uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), intraocular pressure (IOP), central macular thickness (CMT), IOL tilt on ultrasound biomicroscopy (UBM), and pseudophakodonesis on slitlamp and UBM.


The most common cause of aphakia was complicated cataract surgery (50%). The mean preoperative UCVA in logarithm of minimum angle of resolution (logMAR) was 1.59±0.24 and 1.63±0.26 in group 1 and 2, respectively (P=0.45). There was significant improvement in UCVA in both groups (P=0.001) at 6 months (group 1: 0.33±0.17; group 2: 0.22±0.10); the improvement being greater in group 2 (P<0.05). Mean percentage endothelial cell loss and IOP change were comparable. Mean CMT (μm) was 250.95±23.98 and 225.85±21.13 in group 1 and 2, respectively (P=0.009). Pseudophakodonesis was more in group 1 as assessed on slitlamp (P=0.037) and as assessed on UBM (P=0.046). Macular edema was the most common complication seen more in group 1.


Intrascleral haptic-fixated IOL provides more stable fixation, better visual outcome, and lesser complication in comparison with sutured transscleral-fixated IOL.
