The most modern technique for cataract surgery is laser cataract surgery with phakoemulsification. This technique is the easiest on the eye, and most precise.
New IOL's (intraocular lenses) can act like bifocals or trifocals when used during laser cataract surgery. This leads to less need for glasses after surgery.
Laser cataract surgery requires lens implantation, and the newer lens implants can provide near and reading vision. One type of implant that can accomplish this is the Crystalens Accomodating IOL.
New technology for lens implant (IOL) calculations is available to ensure that patients will be more independent of glasses after laser cataract surgery
