Corneal refractive surgery to correct myopia, hyperopia and astigmatism has advanced considerably in recent years. Concretely, different surgical procedures for correcting refractive errors in patients without presbyopia have been developed, as excimer laser refractive surgery or phakic intraocular lenses. Depending on the procedure, different specific tests are necessary. For example, in a consultation of refractive corneal surgery is necessary to analyse corneal topography, corneal thickness, as well graduation to know the patient's diopters mainly. Conversely, to implant phakic intraocular lenses in addition to the anterior devices, will be essential to realizing ocular biometry, as well others diagnostic devices considered necessary by the facultative.
Important innovations have been realized in corneal refractive surgery procedure, as the introduction of new diagnostic devices, microkeratomes, the advent of femtosecond LASIK, as improvements in the excimer laser technology to realize the ablation. Likewise, also the SMILE technology has been introduced, a procedure in which laser acts directly on the cornea without performing corneal flap. In addition, there are surface treatments as Photorefractive Keratectomy (PRK) in which corneal surface is ablated directly without performing corneal lenticule. However, not all patients are candidates for the intervention by corneal refractive surgery. Principally, high graduations, reduced corneal thickness or irregular corneal topographies are some of the limitations of corneal refractive surgery. Precisely, when corneal refractive surgery is not recommended, phakic intraocular lenses are an alternative option to correct the visual defect. Concretely, news developments in anterior and posterior chamber phakic intraocular lenses have been realized. Nevertheless, another procedure, especially in patients with presbyopia with age superior to 45 years, has been developed to improve the vision. In the intervention knows as refractive lens exchange, the crystalline lens not opacified is substituted by an intraocular lens to improve vision at all distances. Indeed, from ConsultoriaVisual.com we plan content marketing and social media strategies about the different diagnostic devices necessaries in a consulting of refractive surgery, its surgical procedure, as its visual outcomes in all Spanish speaking countries. Likewise, from our international project we edit contents for the diffusion of postgraduate courses and master’s degrees to academic community receive more information about the different training programs.
