ASCRS Issues LASIK Screening Guidelines
Who’s an ideal or not-so-ideal candidate for LASIK? What can patients expect from LASIK? The American Society of Cataract and Refractive Surgery addresses these and other issues in its new “LASIK Surgery Screening Guidelines for Patients.” The guidelines explain that before evaluating patients for surgury, most doctors have patients stop wearing soft contact lenses for 3 days and GP lenses for up to 3 weeks (or more in some circumstances). You can download a PDF of the full-text guidelines at

Stem Cells May Help Fight Retinal Disease
One day, doctors may be able to use adult stem cells to treat retinal disorders, such as diabetic retinopathy. Researchers at the University of Florida have found that stem cells in the bone marrow of adult mice can build blood vessels. The mice received bone marrow transplants of stem cells that were genetically engineered to glow green. Researchers were able to trace the origin of new blood vessels that formed in the animals' retinas back to the stem cells they had infused because the vessels glowed green. Nature Medicine published the finding in its June issue (
Readers Write Back: CRT Lens-Maker Answers Critic
Last week, Dr. Alan Saks criticized the practice of orthokeratology (also known as corneal refractive therapy [CRT]) and practitioners who promised permanent results. The following letter, edited for space, is in response to Dr. Saks’ comments.

First, anyone who purposely misleads a patient about the safety, efficacy or performance expectations of any product or procedure is clearly violating accepted standards of care.

Second, Dr. Saks is correct that one reason patients opt for refractive surgery is to avoid the hassles of contact lens care. However, our research suggests that some more important reasons include: contact lens discomfort due to dry eye; an aversion to surgery; or patients who are too young. For these people, overnight contact lens corneal reshaping may be a better option.

Third, Paragon’s CRT product and system has been shown to be safe and effective. I think that once Dr. Saks reviews the clinical data assembled by some of the most respected institutions and practitioners, he may take a different view.

And, finally, the name challenge. Paragon chose CRT because consumer and practitioner research supported its use. The term was more descriptive for consumers, and it reinforced the ongoing need for professional eye care by the use of the word “therapy.” For practitioners, CRT has stimulated important discussions regarding today’s science and technology as compared to the technology that existed when the term orthokeratology was introduced.

Fitting Tip: Selecting Lenses for Corneal Reshaping
To determine the appropriate lenses for corneal reshaping, you can use: Although I’m not aware of any studies comparing these methods, it stands to reason that the latter two, especially using fluorescein patterns, would yield the most efficient results. --The editor
