Head inversion technique to restore physiological conjunctival structure for surgical treatment of primary pterygium.

We describe a new surgical technique to treat primary pterygium, the head inversion technique, with its surgical outcomes. Seventy-five eyes of 75 consecutive patients with primary pterygium undergoing surgical treatment were included. The pterygium head and body were bluntly separated from the cornea and inverted onto the nasal conjunctival area.

Prevalence of seropositivity for hepatitis C virus in cataract patients and the general population.

Mechanical detachment of the anterior hyaloid membrane from the posterior lens capsule.

Design: Prospective nonrandomized interventional comparative trial and comparative human tissue study.

Participants: Thirty-eight eyes of 32 patients undergoing primary pars plana vitrectomy combined with cataract extraction and intraocular lens implantation and 3 eye bank eyes for histopathologic examination.
