Purpose
To compare clinical outcomes and rotational stability of toric implantable collamer lens (TICL) and toric implantable phakic contact lens (TIPCL).
Setting
Tertiary-care eye-center
Methods
Chart-review of all TICLs and TIPCLs implanted by a single surgeon (S.T.). Implant sizing according to manufacturer’s recommendation, however, 15 TIPCLs were 0.25mm larger than recommended to increase vaulting.
Results
Eighty-four TICLs and 98 TIPCLs were identified and yielded excellent refractive and visual results.In total, 15 (8.2%) rotated lenses were recorded; 2 (2.4%) TICLs and 13 (13.3%) TIPCLs (p=0.013).Average TICL size was larger than TIPCL size (p<0.001).Rotation was positively correlated with Cyl and negatively with ACD but not with vaulting (p=0.001, r=0.253; p=0.011, r=-0.193; p=0.488, r=-0.057; respectively).Vaulting was positively correlated with preoperative ACD (p=<0.001, r=0.329).In eyes with a rotated TIPCL, preoperative Cyl was higher and ACD was shallower than in eyes with a stable TIPCL (p=0.001 and 0.007, respectively). Increasing the implant size had no significant effect on rotation rate (p=0.685).
Conclusions
While both implants were safe and effective in highly myopic eyes, TICL rotated less frequently than TIPCL requiring fewer secondary interventions. No threshold for vaulting was found. No case of acute glaucoma or cataract induction was observed.
