Surgical treatment of low vision.

Recent advances in technology are driving a renewed search to find surgical solutions for low vision rehabilitation. The scope of surgery is now being pushed beyond the initial goal of repairing existing anatomical structures. Today, the goal for vision rehabilitation is no less than replacing damaged ocular tissues with artificial ones. Surgical management of low vision may be subdivided into two categories, those procedures aimed at restoring ultrastructural visual function and those aimed at enhancing visual acuity of the residual retina with various levels of magnification. This paper briefly reviews advances in ultrastructural restoration by repair and considers in more detail enhanced acuity through magnification or replacement.
