Embodiment Construction

[0047] figure 1 The general structure of eye 1 is illustrated. The optical path through which incident light travels includes the cornea 140, the pupil 160 defined by the iris, the lens 100, and the vitreous humor. These optics direct light to the retina 170 .

[0048] figure 2The lens 200 is illustrated in more detail. Lens 200 is sometimes referred to as a crystalline lens because the a, b, and g crystalline proteins make up about 90% of the lens. The lens performs several optical functions in the eye, including its dynamic focusing ability. The lens is a tissue unique to the human body that continues to grow in size during fetal life, after birth, and throughout life. The growth of the lens is achieved by the growth of new lens fiber cells originating in the germinal center on the equatorial periphery of the lens. Lens fibers are long, thin transparent cells, typically between 4-7 microns in diameter and up to 12 mm in length. The earliest lens fibers are located in...

Abstract

A method for integrated eye surgery can include determining a cataract-target region in a lens of the eye; applying cataract-laser pulses to photodisrupt a portion of the determined cataract-target region; determining a glaucoma-target region or an astigmatism-target region in a peripheral region of the eye; and applying surgical laser pulses to create one or more incisions in the glaucoma- or astigmatism-target region by photodisruption; wherein the steps of the method are performed within an integrated surgical procedure. The laser pulses can be applied before making an incision on a cornea of the eye. The integrated surgical procedure may involve using the same pulsed laser source for three functions: for photodisrupting the target region, for making an incision on the capsule of the lens and for making an incision on the cornea of the eye.

Description

technical field [0001] This document relates to techniques, devices and systems for integrating cataract surgery with glaucoma or astigmatism surgery. Background technique [0002] Cataract surgery is one of the most commonly performed ophthalmic procedures. The main purpose of cataract surgery is to remove the defective lens and implant an artificial lens or intraocular lens (IOL) to restore some of the optical properties of the defective lens. In general, IOLs are capable of improving light transmission and reducing scatter, absorption, or both. [0003] A widely practiced form of cataract surgery involves ultrasound-based emulsification cataract extraction. During this type of surgery, a lens probe is used through an incision into the lens of the eye. The probe generates ultrasound that breaks the lens into small fragments, thereby causing it to emulsify. Remarkably, this procedure has remained largely unchanged over the past two decades. During phacoemulsification-b...
