Abstract

Purpose : To investigate the tilt and decentration of intraocular lens (IOL) implanted by flanged intrascleral fixation (FF) and sutured fixation (SF) using novel swept-source anterior segment optical coherence tomography(AS-OCT).

Methods : 32 consecutive eyes of 31 patients who had implantation of IOL by FF (20 eyes) or SF (12 eyes) were enrolled. Each operation was performed by one surgeon. After IOL implantation, tilt and decentration were evaluate by AS-OCT. Also 15 eyes of 10 patients who had common cataract surgery, IOL implantation into the capsule bag, were imaged as a control.

Results : The mean IOL tilt were 6.67 degree in FF group, 7.25 degree in SF group, and 4.79 degree in control group. The mean IOL decentration was 0.47mm, 0.45mm and 0.20mm, respectively. The tilt and decentration of IOL in FF and SF group were significantly greater than control group (P<0.01, P=0.015). There was no statistically difference between FF and SF group in tilt and decentration of IOL (P=0.53, P=0.68). In FF group, the decentration of IOL is significantly shorter by trimming of haptics (P=0.04). Tilting of more than 10 degrees was present in 2 eyes (10%) after FF and 2 eyes (16.6%) after SF. No IOL decentration greater than 1.0mm was seen in each group.

Conclusions : There were no differences in tilt or decentration between flanged intrascleral fixation and sutured fixation. Although the both technique were inferior to common cataract surgery in tilt or decentration of IOL, these are useful for IOL implantation without severe IOL dislocation.
