| | Post-LASIK ectasia is not only increased by central corneal thickness
| | No existing scientific evidence validates the presumption that thinner preoperative corneal thickness independently increases the risk of post-LASIK ectasia, as long as intraoperative pachymetry is performed to guard against a thicker-than-expected flap. In fact, thin corneas in eyes with normal topography appear to be biomechanically strong. Routine preoperative topographic screening should be performed to detect abnormalities that suggest an increased risk for post-LASIK ectasia. | |  |

| | When screening patiens for keratectasia risk, corneal biomechanical measurements are helpful
| | Ophthalmology Times | | Researchers are looking into corneal biomechanics as a means to screen patients for keratectasia. An expert reviews signal interpretation from a non-contact applanation tonometer as it relates to corneal biomechanical indices such as corneal hysteresis and also discusses improved signal patterns that may result in more meaningful corneal biomechanical analysis than previously proposed metrics. |
| | Risk of visual symptoms postLASIK is not predicted by large preoperative pupil size
| | Ophthalmology Times | | A prospective study including 51 patients who underwent bilateral wavefront-guided LASIK for low to moderate myopia assessed visual symptoms at follow-up visits through 12 months after surgery. There was no evidence that large preoperative pupil size correlated with increased risk of unwanted postLASIK symptoms. |
| | Refractive surgery: Advanced optical coherence tomography an integral diagnostic tool
| Modality can reveal anatomic features missed by other screening instruments, says physician
| | Ophthalmology Times | | Advanced optical coherence tomography (OCT) devices used in routine screening of refractive surgery candidates can enable clinicians to obtain better results or determine if there is a reason the surgery should not take place. Advanced OCT imaging can reveal anatomic features missed by other screening instruments. |
| | Excimer, femtosecond lasers combine for LASIK with 'excellent' outcomes
| With advanced LASIK procedure, patients were 'very satisfied' with their enhanced vision, study finds
| | Ophthalmology Times | | An advanced LASIK procedure that uses an excimer laser and femtosecond laser (CustomVue iLASIK, Abbott Medical Optics) is safe and effective, and it provides excellent refractive outcomes, based on 1-month results of an ongoing, multicenter, prospective, non-comparative evaluation of 20 patients. |

| | WaveLight AG announces news of excimer, femtosecond lasers
| | Ophthalmology Times E-News | | Japanese authorities have granted WaveLight AG regulatory approval to market its 200-Hz excimer laser system (Allegretto Wave) for use in wavefront-optimized LASIK treatments of myopia and myopic astigmatism there, according to the company. |
| | | LASIK research continues in NEI/NIH grant by Kansas State professor
| | Ophthalmology Times | | Gary Conrad, PhD, has received a 4-year grant renewal of $1.48 million from the National Eye Institute for the National Institutes of Health (NEI/NIH) to study the cornea. Dr. Conrad is a university distinguished professor at Kansas State University's Division of Biology. |
