Ghostbusters Look for Cause of Ectasia

Ectasia after LASIK  Mario Oyarzún MD and Luis Bravo MD  Letter to Journal of Cataract & Refractive Surgery When we saw the article by Binder, we expected to find the answer to many questions about how to predict the patients at higher risk for developing corneal ectasia after laser in situ keratomileusis (LASIK). Perhaps a magical formula would be described. After reading the excellent review by Binder, we see that, unfortunately, the answer to the predictive question still eludes us....

Eye Surgery Deemed Too Risky for NHS

Watchdog says the chances of damage in treatment do not justify widespread use By Sam Lister MOVES to make laser eye surgery available on the NHS are likely to be blocked by the Government’s clinical watchdog amid growing concerns over its long-term safety for patients. A year-long review by the National Institute for Clinical Excellence (NICE) into the procedure known as Lasik, which is currently available only at private clinics, has concluded that current evidence on the treatment’s safety does...

Longer Discontinuance of Rigid Contact Lens Use Before LASIK Surgery Recommended

Medical Devices & Surgical Technology Week A study published in the Journal of Cataract and Refractive Surgery suggests that rigid contact lens users should stop using contacts and switch to glasses 3 to 6 weeks before having pre-LASIK examinations, rather than the traditional 3 weeks. The study found that only 56% of eyes (31 of 55) achieved a stable refraction after 3 weeks, but 78% were stable after 6 weeks, said study author Patricia Tsai, MD, a fellow at the...

Cornell University: "LASIK not worth it"

The Risks of LASIK Corrective Eye Surgery: A Mass Transfer Approach to a Universal Concern By:   Julia Ferullo Kellly Ruggles Bina Lokchander Christina Siryk Puneet Panda Although there are social and aesthetic benefits to the surgery, such as having no need for glasses or contact lenses, the slight risk of complications is a heavy one to take.  Since LASIK is an elective procedure and thus is not covered by many insurance plans, patients pay as much as $1,000 to $2,000...

Corneal Nerve Damage Continues to Increase 2-3 Years After LASIK

Both subbasal and stromal corneal nerves in LASIK flaps recover slowly and do not return to preoperative densities by 3 years after LASIK. The numbers of subbasal nerves appear to decrease between 2 and 3 years after LASIK. The orientation of the regenerated subbasal nerves remains predominantly vertical.

A Mysterious Tale: The Search for the Cause of 100+ Cases of Diffuse Lamellar Keratitis

Publishing an anonymous article in which the author is not identified in a peer reviewed journal may seem inconsistent. However, this mysterious tale can, I believe, be extremely instructive for all readers, especially since it leads to no firm, clear-cut conclusion. I expect considerable correspondence after this article is published. The author requested anonymity for one simple reason: the risk of exposure for litigation with such an honest and revealing narrative.  After consultation with members of the JRS Editorial Board,...

Surgeons Describe a 5-8% Flap Complication Rate for Lasik

Preventing LASIK Buttonholes Steep corneas and surface dryness increase patient risk Balamurali K. Ambati, MD, and Alan N. Carlson, MD LASIK is now widely performed, with an estimated 1.5 million procedures performed last year.1 Flap complications have been reported in 5% to 8.7% of cases.2 The buttonhole, occurring at a rate of 0.3% to 2.6%, is one of the more serious flap abnormalities because it results in loss of BCVA.3-6 A buttonhole in the flap occurs when the microkeratome blade...
