Many LASIK and refractive surgeons are now using Corneal Collagen Crosslinking with Riboflavin (C3R) as a treatment for patients with keratoconus. Recent evidence and studies are showing that Corneal Collagen Crosslinking with Riboflavin (C3R) strengthens the corneal structure and can help prevent the progression of keratoconus. C3R works by increasing collagen crosslinking, giving the cornea greater ability to withstand degeneration that occurs in diseases such as kerataconus. The newly strengthened cornea protects against the bulging out and becoming steep and irregular, consequence of advanced keratoconus.

There are two common forms of wavefront LASIK. These are known as Wavefront Optimized LASIK and Wavefront Customized LASIK. Some excimer laser systems offer the surgeon the choice between either of these or even allows the surgeon to use both of them.

LASIK Wavefront surgery continues to advance in technology and provides over a million eyes with excellent vision every year in the United States. Despite its phenomenal success, LASIK surgery is not without its controversy and patients can often be confused by the marketing information that is provided to patients. LASIK technology and the excimer laser systems used in LASIK surgery is one area of some confusion.

In regards to LASIK laser vision correction, there are several technologies that are important to consider. The first is the excimer laser system that will be used. All excimer laser systems are not equal. It is safe to say that regardless of the skill of the surgeon, any excimer laser system in use prior to 2001 is definitely outdated and cannot provide an adequate level of accuracy and performance. It is generally recommended for a patient to have wavefront correction unless the surgeon can provide a reason that this laser vision correction procedure would not be ideal.

Unlike ten years ago, today’s world of vision correction is filled with options. Many people think that they can choose between glasses, contacts, and LASIK. The truth is that there are now numerous methods and technologies and no single option fits everyone.

While I will refer to LASIK surgeons in this article, the truth is that a surgeon who performs LASIK only may not be the best choice. LASIK is the best choice for some people but other people might require Crystalens or Restor or Visian or PRK or some other vision correction procedure. If a LASIK doctor does not offer these choices, the LASIK candidate may be given the choice that is not in his/her best interests. Find out what options are available to you and which surgeons offer those choices. If the LASIK doctors all recommend LASIK, then you will need to choose the best LASIK surgeon. If another option is a better choice, then the best LASIK surgeon may not help you.

The billion dollar Hubble Telescope has been assisting astronomers for nearly two decades now, gathering information about our own Milky Way galaxy and the rest of our universe. The entire project has not been without problems, however. Shortly after its launch in 1990, it was discovered that the mirror contained significant spherical aberration that affected the performance of the telescope. A system was developed called COSTAR, Corrective Optics Space Telescope Axial Replacement, which used two mirrors in the light path to correct for the aberration in the main mirror. With this adaptation, astronomers could achieve the accuracy and clarity that they were hoping for.

Adaptive optics relies upon a secondary set of mirrors that are in place to adjust for errors within the main optical system. While the Hubble is one example of this, our own eyes can benefit from the advances made through adaptive optics. More »
