Abstract

An anterior chamber maintainer (ACM) is fastened to the cornea of a patient's eye at one or more, or potentially two or more, points of contact. The ACM can be inserted through a first and second incision. The ACM can be fastened to each of the two incisions using, for example, friction surfaces, ridges, a malleable tip, magnets, a segmented tip, or other types of fasteners. The ACM includes openings to provide irrigation solution to maintain the volume of the patient's eye during cataract surgery. The shape of the openings can be customized to reduce the amount of turbulence caused by the irrigation solution. By fastening the ACM to the cornea, the ACM is less likely to shift around or become dislodged from the eye during surgery. The ACM can be integrated with iris retractors to hold the position of a floppy iris during surgery.

Dependent claims

A method for using an anterior chamber maintainer, the method comprising:

cutting a first incision at a location of a cornea of an eye;
cutting a second incision at a different location of the cornea;
cutting a third incision at another different location of the cornea;
inserting the anterior chamber maintainer through the first incision, the anterior chamber maintainer being a tubular structure including a first section, second section, and third section adjacent to the first section and the second section;
fastening the first section to the first incision;
fastening the second section to the second incision such that at least a first opening directed in a first direction a second opening directed in a second direction in the third section are positioned inside the eye, wherein the first direction is different than the second direction;
fastening the anterior chamber maintainer to the third incision;
directing fluid in the first direction through the first opening into the eye;
and
directing fluid in the second direction through the second opening into the eye.
