Purpose
To report clinical experience with a modified toric plate-haptic lens (VisTor, Hanita
Lenses) suitable also for 4-point scleral fixation in eyes without capsular support.
Setting
All surgeries were performed between 2022 and 2023 by two surgeons (E.I.A, A.B) at
two medical centers. The study conforms with the Decleration of Helsinki and was approved by
the Institutional Ethics Committee, Meir Medical Center, Kfar Saba, Israel.
Methods
The commercial VisTor lens design was modified by adding two positioning holes in
the lens haptic to facilitate 4-point fixation. The lens axis was marked preoperatively, and the
insertion points of the sutures were marked 2mm from the limbus and 2mm on each side of the
toric marks. Prolene 6-0 or 7-0 sutures were inserted through the sclera and threaded through the
designated holes in the intraocular lens (IOL) haptics. Four-point fixation was achieved by
creation of 4 external flanges.
Results
Fifteen lenses were implanted in 15 eyes lacking capsular support. One case was lost to
follow up and excluded from final analysis. The average age was 48 (SD 22, range 26-79). In 9
eyes surgery was secondary implantation in aphakia, in 3 eyes it was combined with crystalline
lens removal, and in 3 eyes it was combined with IOL exchange. The final position of the IOL
was within 4 degrees of the planned axis in all eyes. No tilt was noted post operatively and
satisfactory visual improvement was achieved in all cases but one, in which vision loss was
related to advanced glaucoma.
Conclusions
Four-point scleral fixation of a plate haptic IOL provides precise and stable IOL
positioning with no tilt and accurate toric correction in eyes lacking capsular support.
