TOCULAR

PRECISE angle alignment of toric IOLs

During implantation of toric IOLs precise angle alignment of the lense in the capsule is required For this procedure TOCULAR is offered by HAAG-STREIT SURGICAL.


THE RETICLE

Precise alignment

TOCULAR is a rotatable wide angle ocular with an integrated reticle that can be rotated manually via a sterilizable knob. For best visibility the reticle is clear in the center of the visual field. It allows an IOL alignment of better than +/- 2°.

PRE-OPERATIVE WORK

Marking of the eye

Prior to the operation the astigmatic angle has to be determined with a keratoscope or a biometer. We recommend the use of the Haag-Streit LENSTAR LS 900. The vertical and/or horizontal coordinates are ink-marked on the eye with a sterilizable pre-marker as the Davis pre-marking system distributed by John Weiss.

DURING SURGERY

Alignment of the toric IOL

After implantation of the IOL, the microscope zoom is adjusted to show the ink-marking in the visual field of the oculars. With the knob on the TOCULAR the reticle is turned to align the large scaled markings with the ink-marks on the eye. Now the IOL can be brought into position using the medium and small reticle markings.
