Abstract
Treatments to improve ocular conditions such as presbyopia are provided. Structural (mechanical) weakening of the sclera is accomplished through the formation of a 3-D pattern of laser foci in the sclera resulting in an increase in the range of ocular accommodation.
Claims9
A method of structurally weakening the sclera in an eye to improve a presbyopia condition of the eye, the method comprising:
- using a pulsed laser system to generate a three-dimensional (3-D) pattern of focused laser pulses in the sclera, the laser pulses passing noninvasively through a conjunctiva layer in the eye to a plurality of foci in the sclera to structurally weaken the sclera at the foci, thereby producing a 3-D pattern of structurally weakened regions in the sclera that increases the eye's range of ocular accommodation and improves the presbyopia condition;
- wherein each of the structurally weakened regions in the sclera has a 3-D ellipsoidal shape.
