Preexisting Psychiatric and Personality Disorders Can be a Major Source of Dissatisfaction After LASIK

A recent study done at the US Navy Refractive Center in San Diego was performed to determine the source of patient dissatisfaction after LASIK. The study confirmed that the overwhelming majority of patients were satisfied with the results of their LASIK surgery. An important predictor of dissatisfaction was the preexistence of psychiatric and personality disorders. Specifically mentioned was the presence of depression or a negative outlook. This study points out the importance of screening patients for these disorders and for patients to have realistic expectations. http://www.medpagetoday.com/MeetingCoverage/AAO/7323

Measurement of Depth of Intacs

A recent article explores the use of Intacs in keratoconus:

Measurement of Depth of Intacs Implanted Via Femtosecond Laser Using Pentacam
Journal of Refractive Surgery Vol. 25 No. 4 April 2009

Günhal Kamburoglu, MD; Aylin Ertan, MD and Osman Saraçbasi, PhD

Thirty-two eyes of 23 keratoconic patients receiving Intacs intrastromal corneal ring segments implanted by femtosecond laser were included in the study. The depth of intracorneal channel and Intacs segments were measured for 7 predetermined points at 1 week and 1 year postoperatively using Scheimpflug images.
Mean achieved intrastromal channel depth exceeded the intended parameter by 6.5 µm to 69.0 µm. The standard deviation varied between ±13.5 µm and ±44.2 µm. The segment depth decreased at the end of the first postoperative year in all measured points, and the change was statistically significant at the superior, inferior, and temporal sides of the Intacs. The degree of change was not correlated with size of the Intacs, preoperative central corneal thickness, and mean keratometric values.

CONCLUSIONS
Intacs started out deeper than intended and tended to shallow over time. I had one patient who had erosion of their Intac segment into their anterior chamber which may have been a result of deeper than intended placement. This study has important implications for surgeons who perform Intacs in the treatment of keratoconus.

Treating Epithelial Ingrowth with the YAG Laser

Jorge L. Alió, MD described the use of the YAG laser to treat epithelial ingrowth after LASIK as an alternative to flap lifts in a recent issue of Refractive Eyecare. Early treatment of mild-to-moderate epithelial ingrowth with the Nd:YAG laser promises a simple way to eliminate a vexing problem and, possibly, prevent the development of more serious problems.
Instead of lifting the LASIK flap, refractive surgeons can treat most moderate epithelial ingrowth and restore patients’ lost visual acuity with a laser commonly used after cataract surgery. This low-energy, effective procedure uses the workhorse of ophthalmic lasers to spare patients more invasive surgery and avoid the risks of further complications from a flap lift
