Patenting Medical Procedures

Arch Ophthalmol. 2000;118(8):1140. doi:

The article on retinal sparing through a modified laser technique by Roider et al1 is to be commended for broaching a subject that has concerned retinal laser surgeons for many years: How to avoid tissular destruction beyond the intended scar formation. Localizing burns to the pigment epithelium is desirable in many cases, but not in all. Perhaps diabetic retinopathy is a situation in which the intended decrease in retinal metabolic requirements is better served with more extensive destruction of retinal tissue.
