Corneal biomechanics and small-incision lenticule extraction: What is the evidence?With the currently available clinical evidence, we can ensure that different biomechanical changes occur after SMILE, LASIK or PRK, but we cannot ensure that there is a superiority of one technique over the others in terms of mechanical stability.
Enhancing rate of re-epithelialization after LASIKResults of a randomized controlled trial suggest that treatment with topical trehalose 3% ophthalmic solution might increase the rate of re-epithelialization after PRK.
Touch-up techniques following SMILEResearch shows that enhancement rates after LASIK range from approximately 7.8% to 20%, with regression of approximately 1 diopter after 10 years.
Epithelial thickness mapping in the care of refractive surgery patientsCorneal epithelial thickness mapping may become an easy and objective tool in the diagnosis of biomechanically unstable corneas and perhaps a multitude of anterior segment disorders.
PRK enhancement after SMILE favorable after short follow-upSurface ablation performed with mitomycin-C (MMC) seems to be a safe and effective technique for treating residual refractive error after myopic SMILE, said Martin Dirisamer, MD.
LASIK, PRK enhancements yield similar safety, efficacy, predictabilityWavefront-guided LASIK and wavefront-guided PRK following previous keratorefractive surgery demonstrate similar safety, efficacy, and predictability and result in comparable wavefront outcomes.
How to manage vision changes over time post-LASIK
How to manage vision changes over time post-LASIKHow often have you heard a post-LASIK patient say his surgery “isn’t working anymore” or it has “expired?” While the corneal tissue that was ablated is gone forever, eyes can change over time, and laser vision correction does not stop time.
Preparing your patient for PRKPhotorefractive keratectomy (PRK) was the original excimer laser procedure approved by the FDA—and is still a safe and effective treatment of refractive errors. PRK has the benefits of no-flap creation; therefore, there is no risk of flap complications.
Haze after PRK, LASIK tied to faulty epithelial regrowth
Haze after PRK, LASIK tied to faulty epithelial regrowthPoor regeneration of the epithelial basement accounts for most 'late haze' associated with PRK, LASIK, infections, or corneal transplants. Proper excimer laser maintenance may reduce irregularities.
Pulse technology boosts all-laser PRK for one-step, no-touch ablation
Pulse technology boosts all-laser PRK for one-step, no-touch ablationA transepithelial PRK (TransPRK) procedure (SmartSurface, Schwind eye-tech-solutions) provides the benefits of one-step, no-touch surface ablation plus rapid visual recovery, said Diego de Ortueta, MD.
