Lasik has been the most discussed process for vision correction - and it certainly does wonders for the near sighted individual. Many middle-aged folks have not had many good options so far. Researchers are constantly improving on techniques to help this demographic.
In one technique, researchers used lasers to re-engineer the eyeball, either by cutting slits, into which tiny lenses can be inserted, or by altering the shape of its outer layer. Leading this field is Technolas Perfect Vision of Germany born out of a joint venture between Bausch & Lomb's Refractive Surgery unit and 20/10 Perfect Vision.
They have patented a process called INTRACOR a technique that provides flapless intrastromal correction using the TECHNOLAS® Femtosecond Workstation, to achieve reshaping of the cornea.
INTRACOR presbyopia procedure is based on a gentle, localized change in corneal curvature. The epithelium and Bowman’s membrane both remain fully intact.
Presbyopia correction with INTRACOR® lasts approximately 20 seconds. During the procedure, gas bubbles form in the cornea, and the patient's vision is blurred for 2 to 3 hours. When the bubbles dissolve, the cornea clears and the distance visual acuity returns. After that, the patient can immediately notice the change in near visual acuity. On the first day after sugery, most patients experience a gain in near visual acuity.
