Purpose
To compare the visual and refractive outcomes, predictability and rotational stability following implantation of a monofocal toric IOL with textured haptics in eyes with normal versus high axial lengths.
Setting
It is a two arm, restrospective study conducted at Nethradhama Superspeciality Eye Hospital, Bangalore.
Methods
This study included 114 eyes of 114 eligible patients who underwent femto assisted cataract surgery followed by implantation of the Hoya VivinexTM monofocal Toric IOL (Model XY1 ), of which 62 and 52 eyes belonged to normal (<23.9 mm) and high ( =/> 24mm) axial length groups respectively. One week and 3 months post-operatively, clinical outcomes and rotational stability of the toric IOL was evaluated using an dilated clinical photography in retro illumination using the Eye Cap ( Image Capture and Management System, Haag- Streit, USA) on which an online protractor tool (available at https://www.ginifab.com/feeds/anglemeasurement/) was superimposed.
Results
All pre-operative ocular parameters were matched for both the groups, except for the axial length, anterior chamber depth & white to white diameter, which were significantly greater in the high myopia group. 3 months post-op, percentage of eyes achieving refractive astigmatism accuracy within ≤0.50 D, was 100% (n=62) in the normal versus 98% (n=51) in the high axial length group. At 3 months, 100% eyes were <5º of intended axis in the normal axial length group, compared to 96.15% eyes in the other group. The average change in post-op rotation from 1 week to 3 months was 0.28 ±0.09, and 0.30 ± 1.11 degrees in the normal & high axial length groups respectively. No eye required re-positioning of IOL for significant post-op rotation.
Conclusions
At 3 months, no significant differences were observed for clinical outcomes and post-op rotational stability between eyes with normal and high axial lengths, suggesting the potential advantage of textured haptics in achieving stable post-operative positioning in the capsular bag.
