Jose Ignacio Barraquer (Bogota) is the pioneer of the lamellar refractive corneal surgery. He began his endeavors 35 years ago and thanks to his enthusiasm, organizational talent and technical genius procedures have been developed which allow us to alter in a predetermined way the radius of curvature of the corneal surface.

Corneal Haze After Refractive Surgery
2008Loss of corneal clarity (haze) after refractive surgery can be a serious condition, leading to decrease in VA, myopic regression and irregular astigmatism. Most cases of post-PRK haze are clinically insignificant and self-limiting. In addition to haze post-PRK, haze can also be seen after LASIK, epi-LASIK, and LASEK.

Equation for Corneal Asphericity After Corneal Refractive Surgery
Journal of Refractive Surgery, 2003ABSTRACT PURPOSE: To determine the exact theoretical asphericity after refractive surgery when the parabolic approximation of the Munnerlyn formula is utilized. METHOD: From a least-square analysis and considering the conicoid model for anterior cornea, we calculated the final asphericity (p '-factor) from the preoperative ...

Refractive corneal surgery with lasers
Current Opinion in Ophthalmology, 1996Laser refractive surgery is on one hand in a phase of consolidation regarding the routine treatment of mild to moderate myopia by means of spheric excimer laser photorefractive keratectomy. On the other hand, exciting new developments are taking place in the field of high myopia, myopic astigmatism, and new alternative lasers.

Biomechanical Modeling of Refractive Corneal Surgery
Journal of Biomechanical Engineering, 2005The aim of refractive corneal surgery is to modify the curvature of the cornea to improve its dioptric properties. With that goal, the surgeon has to define the appropriate values of the surgical parameters in order to get the best clinical results, i.e., laser and geometric parameters such as depth and location of the incision, for each specific ...

Mitomycin C in Corneal Refractive Surgery
Survey of Ophthalmology, 2009Mitomycin C has played a deciding role in the current revival of excimer laser surface ablation techniques. We review the literature regarding mechanism of action of mitomycin C, histological effects on the cornea, and indications, dose, exposure time, and toxicity of mitomycin C in corneal refractive surgery.

Mechanical methods in refractive corneal surgery
Current Opinion in Ophthalmology, 1996The past year has seen considerable advances and debate with regard to several new and some established mechanical means of refractive surgery. Lamellar in situ keratomileusis is gaining increased interest, especially for the treatment of moderate and high myopia, although considerable questions still exist with regard to its safety, predictability ...

Hawaii medical journal, 1997
Excimer lasers and high technology instrumentation have ushered in a new era of vision improvement surgery in Hawaii, replacing the more traditional forms of refractive surgery: cataract surgery, corneal transplant surgery, and radial keratotomy. Corneal surgery has been enhanced by new techniques of microsurgery and a more effective tissue procurement

Wavefront's role in corneal refractive surgery
Clinical & Experimental Ophthalmology, 2005AbstractIn the 5 years since the first wavefront‐based LASIK treatment on normal eyes, the ophthalmology profession has had to confront a new language based on astronomy, optics and mathematics. Over this time wavefront technology has been used for diagnosis and treatment, and its application has made the profession define what is meant by good vision,

Mechanical methods in refractive corneal surgery
Current Opinion in Ophthalmology, 1993Keratorefractive surgery has developed rapidly over the past decade. For patients with aphakia, however, posterior chamber lenses are safer and more predictable than refractive corneal surgery; myopia is the greatest challenge to this type of surgery. No technique as yet has an accuracy that is adequate for the general treatment of myopia.
