An Anatomical Study on Transscleral Suture fixation of Posterior Chamber Intraocular Lens

ABSTRACT

We performed an anatomical study on transscleral suture fixation of posterior chamber intraocular lens implantation. Results showed that the relationship of the ciliary sulcus to the overlying posterior surgical limbus differed in the vertical and horizontal meridians. Needles that pierced the ciliary sulcus after being passed perpendicularly through the sclera entered the sclera 0.88+/-0.22mm posterior to the posterior surgical limbus in the vertical meridians and 0.44+/-0.37mm in the horizontal meridians. The scleral exit site of a suture passed from the inside of the eye through ciliary sulcus was 0.90+/-0.12mm posterior to the posterior surgical limbus in the vertical meridians, 0.85+/-0.17mm in the oblique meridians, and 0.45+/-0.10mm in the horizontal meridian.
