Hate Bifocals? See Us for Options

Sunday, October 18th, 2009

When the cause of your eyeglass dependence is nearsightedness, the vision correction options are pretty straight-forward. When there is a need for reading glasses or bifocals, solutions can be more complicated.
Most people develop a condition called presbyopia as they approach age 40. Presbyopia is the inability of the eye to focus at all distances, usually noticed when fine print starts to blur.

Some eye doctors disagree about what causes presbyopia. Most believe stiffening of the eye’s lens contributes to the condition. Other theories suggest that presbyopia could also be related to continued growth of the lens or atrophy of the muscles controlling the lens.

In the past, the usual remedy was to wear reading glasses or special multifocal lenses (bifocal or progressive) for presbyopia. But in modern times, surgical remedies for presbyopia also are available for qualified candidates.

One of the first effective surgical options for presbyopia correction involved producing what is known as “monovision” during LASIK. But other surgical procedures such as conductive keratoplasty or CK also have been approved by the FDA, which gives eye surgeons additional options for correcting this common vision problem.
In some cases, refractive lens exchange (exchanging the patient’s natural lens with a bifocal lens or artificial flexible lens) can solve the problem. The surgical solution for presbyopia continues to evolve. If you would like to explore your options, why not see us for a complimentary evaluation?

Trust but Verify

There are a lot of claims out there by LASIK providers. Of course everyone claims to be the best or offer the best technology. Most of the time, claims about results or number of procedures are completely unsubstantiated making it difficult to compare. If having the highest percentage of 20/20 is your yardstick for success, then CustomVue LASIK from AMO and offered by the Laser Eye Center of Carolina boasts the highest percentage of 20/20 results (98%) ever reported to the FDA and is therefore the best laser and the best LASIK technology. Patients can arm themselves with unbiased information available from the FDA website, All About Vision.com, the Academy of Ophthalmology website and other reputable unbiased sources in helping them to decide where to get their LASIK Eye Surgery in the Raleigh Durham NC area.

iLASIK vs zLASIK: Which is Better?

Sunday, October 4th, 2009

The first all-laser LASIK procedure made use of the IntraLase laser to make the flap rather than a blade. When the IntraLase laser is combined with AMO VISX’s proprietary CustomVue wavefront-guided treatment, the resulting procedure is termed “iLASIK”. The IntraLase laser has gone through several upgrades since it was first developed to improve it’s safety and precision. Because the IntraLase flaps can be made to fit like a “manhole” they tend to be more secure than those cut by a blade. Also, if something interrupts the creation of the flap, treatment can be restarted without any ill consequences. Since the introduction of IntraLase, Ziemer, a Swiss company, has introduced a laser to make LASIK flaps. Dr. Dornic has used both of these lasers to perform LASIK. The Ziemer laser is less expensive but it is not as well refined as the IntraLase laser. While the IntraLase laser can make flaps of varied thicknesses and architecture, the Ziemer laser can only make flaps of 3 different thicknesses and 3 diameters. The Ziemer can also only make flaps that are cut in much the same shape as a blade. They are therefore not as secure as an IntraLase flap. Another limitation of the Ziemer laser flap is that unlike the IntraLase laser, your surgeon cannot see the flap being made. Therefore, the surgeon cannot intercede to correct a problem such as misalignment or loss of suction occurring during the creation of the flap. What this means to the patient is that iLASIK is safer (more customizable flaps, lower risk of small, misshapen, decentered or slipped flaps) and the overall results are better with iLASIK than with zLASIK. If you want the safest, most precise LASIK, choose iLASIK.
