WHAT IS THE REFRACTIVE SURGERY?
Refractive eye surgery is any eye surgery used to improve the refractive state of the eye and decrease or eliminate dependency on glasses or contact lenses. These procedures are designed to correct refractive errors such as myopia, hyperopia, astigmatism and presbyopia.
We have been performing Excimer laser surgery since 1988, and LASIK surgery since February 1995. We upgrade continuously our equipment’s so that we can offer our patients the last available technology to obtain the best optical and functional results.
It is necessary to perform some diagnostic tests prior to establishing the suitability of the patient and to select the proper type of treatment to provide full efficacy and safety for optimal results to be achieved. A wide range of therapeutic solutions for each age range or diopter is to be rigorously studied in order to apply a particular technology in each case. The Castanera Institute of Ophtalmology has all the means to analyze and evaluate visual function and to establish the most appropriate surgical indication.
Corneal topography serves to evaluate and quantify the shape, curvature, and thickness and corneal power. Corneal pathologies can be detected even at very early stages of its evolution, and treatment planning allows us to evaluate patients who are candidates for laser refractive surgery techniques or intraocular techniques.
The Aberrometry is the study of optical irregularities of the eye which directly affect the quality of vision.
Biometrics by laser interferometry determines the ocular length allowing calculation of the power of the intraocular lens implanted.
Endothelial microscopy allows to analyze the morphology and density of the corneal endothelial cell.
The optical and ultrasonic Pachymetry measures the thickness of corneal tissue.
With optical coherence tomography of the anterior segment, the cornea, the iris, the anterior chamber and the central are of thelens are analysed by menas of high-resolution transverse images.
Patients contact lens wearers should discontinue their use prior to the preoperative examination and surgery for 7 days.
