LiangVision.com - OCT Technology

LASIK is now the vision correction procedure of choice for many ophthalmologists worldwide. Instead of removing the surface epithelium with the laser and exposing many nerve endings (as in PRK), the surgeon performing LASIK uses a motor-powered microkeratome to create a "flap." The flap is then lifted and reflected back, allowing a computer guided Excimer laser (cold laser) to use light pulses to remodel the corneal tissue underneath. Afterward, the flap is gently positioned back onto the cornea. Since this procedure is less traumatic to the outer surface of the eye, vision is restored more quickly and the patient's discomfort is reduced. Most patients report greater comfort after surgery and can generally drive two to three days after the surgery.

Optical Coherence Tomography

OCT is an innovative scanning system that produces highly detailed images of the retina, the innermost layer of the interior of the eye. This instrument can “see” below the surface of the retina to examine the retinal layers. These pictures allow Dr. Liang to identify and treat problems in the best possible way.

With the OCT, Dr. Liang can detect glaucoma and other abnormalities of the retina, including age-related macular degeneration (AMD), detached retina, macular holes, diabetic macular edema and more. The OCT never touches the eye, so there is no discomfort and requires only minutes to scan the eye.
