A drill guide to facilitate the second stage drilling of hydroxyapatite orbital implants is presented. The drill guide is adaptable to various drill types. It is nontraumatic and provides excellent, one-handed fixation, eliminating the need for an assistant. It allows for consistent, straight drilling to a predetermined depth and, because it is encased, it protects the patient from injury. The drill guide has been used on 30 patients and is without untoward effects.
