Abstract

The basic instruments for corneal grafting surgery include eye speculum, corneal trephines, needle holders, and a Pierse-Hoskin forceps. However in the recent past, the number of instruments available for corneal grafting has increased considerably. Many of the newer instruments are variations of the earlier designs. Instruments specific for corneal transplantation surgery can be divided into five categories: (i) instruments designed for optimal globe exposure; (ii) instruments specifically designed to cut the recipient and the donor cornea, such as trephines, punches and blocks; (iii) instruments used to secure the donor cornea and to remove and replace lens implants such as forceps, scissors and needle holders; (iv) instruments used to assist in the maintenance and reconstruction of the anterior segment such as cannulae, spatulas and hooks; (v) Qualitative keratometers used intraoperatively to assess the corneal toricity. The suitability and selection of instruments for corneal transplantation is based primarily on specific surgical technique, surgeon’s preference and the expertise.
