Sutureless scleral intraocular lens fixation
Keywords:
lente rígido, afaquia, fijación transescleralAbstract
Surgical aphakia correction is based on several techniques allowing to fix intraocular lenses in the posterior chamber, sutured to the ciliary sulcus or by sutureless transcleral fixation of the haptics. The surgeon will decide when, where and how, as well as the lens type to implant. A case is presented of a male patient with traumatic aphakia of his left eye, finger counting uncorrected visual acuity at one meter and dynamic refraction of +8.00 diopters with best corrected visual acuity of 0.8 by the Snellen chart. Ocular tension was 16 mmHg. Biomicroscopic slit lamp examination of the left eye found traumatic mydriasis. Indirect biomicroscopy did not find any alteration. A three-piece intraocular lens (Tecnis ZA9003) was implanted in the posterior chamber, fixing the haptics to the sclera without the use of sutures. One month after surgery, best corrected visual acuity was the vision unit.
Key words: Three-piece lens; aphakia; transcleral fixation.
