The LASIK industry & the FDA have conspired since LASIK's inception to purposely withhold information vital to the public in making a truly informed LASIK decision. With, The hope is to show you what the industry and FDA would not and did not even think of doing until LASIK casualties started speaking out, and yet, they still did NOTHING.
Surface ablation yielded better biomechanical stability vs. LASIK in study PDF Print E-mail

BARCELONA - Regardless of how thick or thin LASIK flaps are made, the flaps cause a considerable reduction in corneal biomechanical stability compared with surface ablation procedures, according to a study presented here.

"Taking into account biomechanical properties but also visual recovery time and quality of vision, the best option is epi-LASIK, according to our results," Jorge Cazal, MD, said at the winter meeting of the European Society of Cataract and Refractive Surgeons.

In a study conducted at CIMA Eye Clinic, two groups of 25 patients were randomly assigned to undergo epi-LASIK with the Moria Epi-K epikeratome in one eye and PRK or thin-flap LASIK in the other eye.

"At 6 months postoperatively, the LASIK eyes experienced a 48% reduction in corneal biomechanics, while the eyes that underwent surface ablation had only a decrease between 10% and 14%," Dr. Cazal said.

"At 6 months, the LASIK group had the highest induction of high-order aberrations, with [root mean square] of 0.73, compared with 0.25 for the epi-LASIK group," he said.

However, visual recovery was fastest with LASIK, followed by epi-LASIK and PRK. Pain scores were also lowest with LASIK, followed by epi-LASIK and PRK, he noted.
