Cornea/External Disease/Anterior Segment

The Cornea/External Disease/Anterior Segment Service focuses on problems of the ocular surface, including infections of the conjunctiva and cornea, corneal degenerations and other abnormalities of the ocular surface and anterior segment. Corneal transplantation, anterior segment reconstruction, cataract and intraocular lens surgery, refractive corneal surgery and surgery for complicated cataract extraction are performed by this service. Doheny is one of the few ophthalmic centers in the country involved in the FDA-supervised clinical trial testing the efficacy of the excimer laser. This dramatic new laser alters corneal shape, thereby correcting refractive errors and removing corneal scars and other opacities that block vision.

The Cornea/External Disease/Anterior Segment Service offers comprehensive corneal evaluations, medical diagnostic services and computerized topography, which can often be performed during a single visit. Surgical services, as listed above, are coordinated closely with the referring physician. Some of the available diagnostic services include pachymetry, potential acuity measurement, microbiological studies and assessment of corneal topography using computerized corneal modeling technology.

Some of the more common patient diagnoses referred to this Doheny service include bullous keratopathy, corneal ulcer, corneal scarring, corneal astigmatism and cataracts.
