Combined transconjunctival sutureless three-port vitrectomy and scleral fixation of intraocular lens

The aim of this article is to describe an innovative and minimally invasive surgical technique for posterior vitrectomy combined with secondary intraocular lens implantation, using a sutureless scleral fixation Carlevale intraocular lens (I71 FIL SSF Carlevale lens. Soleko IOL Division, Italy).

The technique was conducted with only three transconjunctival sclerotomies and a corneal tunnel to perform intraocular lens explantation, posterior vitrectomy and Carlevale intraocular lens implantation. It is easier, quicker, and less invasive than the traditional technique with conjunctival peritomy, two scleral flaps and five sclerotomies.

Surgery was performed uneventfully on three eyes of three patients. Two of them presented a luxation of the intraocular lens into the vitreous chamber, while one patient presented an intraocular lens subluxation. No complications were observed after a 5 to 8 months of follow-up. The intraocular lenses were well positioned, no conjunctival erosion was noted, and the intraocular pressure remained normal at all stages.

This is the first report of a combined procedure of IOL explantation, posterior vitrectomy and secondary IOL implantation using only three transconjunctival sclerotomies. This appears to be less invasive and it causes less discomfort to the patient. We suggest considering this technique in all those cases requiring a combined procedure in absence of a proper capsular support.
