TLDR
In this article, a line focus on the cornea of an eye is proposed to create radial and circumferential curved incisions, including rectilinear and curvilinear line focus.Abstract:
An apparatus and method for delivering radiant energy beams onto an area of a cornea in a line focus to create a linear incisions. The radiant energy beams may be focused in a linear configuration onto the external surface of the cornea or onto intrastromal areas of the cornea of an eye to ablate the cornea in a radial slot, circumferential curved slot, or lenticular pattern, and thereby modify its curvature and refractive power. The apparatus includes an array of central reflectors and an assembly of peripheral reflectors. Each central reflector is associated with a respective peripheral reflector so that a beam reflected by the central reflector is intercepted by its associated peripheral reflector and is again reflected to precisely incise either external or internal areas of the cornea. Each peripheral reflector has a curved reflective surface to provide a line focus on the cornea, including both rectilinear and curvilinear line focus to create radial and circumferential curved incisions. In a modified embodiment, the assembly of peripheral reflectors and the array of central reflectors rotate to permit lathing of the cornea.read more

Lenticular refractive surgery of presbyopia, other refractive errors, and cataract retardation
TL;DR: In this paper, microsphere formation in non-contiguous patterns or in contiguous volumes works to change the flexure, mass, or shape of the crystalline lens in order to maintain or reestablish the focus of light passing through the ocular lens onto the macular area.

Method and apparatus for analysis and correction of abnormal refractive errors of the eye
TL;DR: In this article, the authors proposed instrumentation to aid in performing refraction-corrective surgery on the conrea, by determining the topography of the anterior surface of the cornea, the determination being in the form of digitized data entered into computer storage.

Method for ophthalmological surgery
TL;DR: In this article, the authors used a scanning laser characterized by ultraviolet radiation to achieve controlled ablative photodecomposition of one or more selected regions of a cornea, which can change the front surface of the cornea from a greater to a lesser spherical curvature, or from a lesser to a greater spherical curvatures, thus effecting reduction in a myopic or in a hyperopic condition.
