Laser/Advanced Technology

Laser-Assisted Cataract Surgery:

  • For decades, cataract surgery, including the first incisions and the breakup and removal of the cataract, were performed by hand. Now, additionally, CNY Eye Physicians and Surgeons, offers the option of femtosecond laser as an adjunct to cataract surgery. 
  • The femtosecond laser emits optical pulses in the realm of a femtosecond—an almost unimaginably short duration (one-millionth of one-billionth of a second). A femtosecond laser can be thought of as a ‘microscalpel,’ cutting and breaking up the cataract on a microscopic scale with an incredible level of precision.

Laser (in office):

  • Retinal PASCAL pattern scanning laser (laser used to treat conditions affecting the light sensing nerve fibers in the back of the eye)
  • Glaucoma laser
    • Selective laser trabeculoplasty (enhances fluid drainage from the eye thereby usually lowering the eye pressure)
    • Laser iridotomy (creates a tiny hole in the peripheral iris which decreases the risk of angle closure glaucoma, a type of glaucoma caused by the iris blocking the drainage system of the eye)
  • "After cataract" laser for capsular clouding (performed after cataract surgery if the thin capsule that holds the new lens implant becomes cloudy)

Diagnostic testing:

  • High definition spectral domain optical coherence tomography (OCT) (provides very detailed information about different parts of the eye using light rays)
  • B-scan ultrasonography (uses ultrasound energy to provide information about the eye)
  • Intravenous fluorescein angiography (dye is injected into the bloodstream and pictures are taken of the eye to provide more information about the circulation of the back part of eye)
  • Ocular photography (photos of the eye)
  • Computerized visual field testing (an interactive test used to determine if there are any parts of the central or side vision that are not working well)
  • Corneal topography (provides information about the surface of the cornea, the clear dome on the front part of the eye that bends the light rays that enter the eye)
  • IOLMaster (laser measurement of eye length to determine lens implant power in preparation for cataract surgery)
