These incisions are known to be the result of eye surgery called radial keratotomy
, a procedure which the patient confirmed she'd undergone 23 years prior to the exam, according to the report, led by Dr.
They are an excellent option in patients with irregular astigmatism such as previous radial keratotomy
Consultations in refractive surgery: IOL calculations following radial keratotomy
Among surgical procedures, arcuate keratotomy
reduces postkeratoplasty astigmatism, but the results of this technique are often unpredictable [3, 4].

for Myopia and Astigmatism, p 309.
During multiple recheck examinations over 4 months, the ulcer was treated by debridement with a sterile cotton-tipped applicator, diamond burr debridement, diamond burr debridement with cyanoacrylate tissue adhesive, and grid keratotomy
with cyanoacrylate tissue adhesive, all performed under anesthesia with eventual resolution of the corneal ulcer.
In sections on setting the stage, surgical techniques and implants, and post-operative considerations and enhancements, they discuss such facets as preparing the ocular surface for cataract and refractive surgery, educating patients, femtosecond laser-assisted cataract surgery, the toric intraocular lens: successful strategies, excimer laser enhancements after intraocular lens surgery, and enhancements with micro-radial keratotomy
or astigmatic keratotomy
Different procedures have been used in refractive surgery which include photorefractive keratectomy (PRK), radical keratotomy
(RK), laser-assisted in situ keratomileusis (LASIK), laser thermal keratoplasty (LTK), small incision lenticule extraction (SMILE) etc.4 Refractive surgeries with laser flap makers were approved by the United States Food and Drug Administration (FDA) in 1999 and femtosecond specifically for flap creation was approved in 2001.5 Femtosecond laser-assisted LASIK (femto-LASIK) is very successful latest innovation in refractive surgery because of its better outcome, long-term stable results, and lesser complications compared to other procedures.6 Femtosecond uses ultra-short duration of the pulses (10-15) causing significantly less damage to the collateral tissues.
(RK) is an old procedure invented in 1974 by Svyatoslav Fyodorov aimed to correct myopia and corneal astigmatism .
