Refractive surgery has become the most rapidly developing field in ophthalmology over the last two decades. Several modern refractive procedures have become available over the last 10 years including phakic intraocular lenses (pIOLs), epithelial laser-assistedin situkeratomileusis (epi-LASIK), wavefront-guided (WG) laser treatments and a few others. Laser and non-laser refractive surgical procedures are currently used to address refractive errors. No single procedure works best for everyone; each one has its own set of advantages and disadvantages. Careful patient selection is the key for optimum visual outcomes. Treatment algorithms have been refined over the years, improving accuracy. Laser technology and delivery platforms are under continuous improvement, leading to increasingly precise results. Further modifications and refinements are ongoing, offering expanding surgical options in this rapidly evolving field.

ABSTRACT Purpose To discuss and summarize the indications, contraindications and results in refractive surgery for keratoconus. Summary Keratoconus is an ectatic corneal disease characterized by a progressive corneal thinning and irregular astigmatism that negatively impact in the visual function and the optical quality of the patients. The refractive surgery in keratoconus has been discussed by several authors. The two primary lines of action are phakic lens implantation and corneal tissue ablation using photorefractive keratectomy. The use of phakic intraocular lenses (IOLs) to correct myopia and compound myopic astigmatism associated with keratoconus is gaining popularity. Recent findings The use of phakic IOLs to correct myopia and compound myopic astigmatism associated with keratoconus is gaining popularity. According to a recent study by our group the safety of this procedure in visual terms is high (post-CDVA/ pre-CDVA = 1.19 ± 0.29). It is also an effective operation (post-UDVA/pre-CDVA = 0.90 ± 0.26). How to cite this article Alio JL, Sanz-Díez P. Phakic Intraocular Lenses in Keratoconus.

The article presents review of actual publications' data concerning surgical correction of presbyopia. The data is presented related to social significance of presbyopia alongside with other disorders of refraction. The techniques applying monovision include thermokeratoplasty and such its modification as laser and radio-frequency thermokeratoplasty. All of them have number of deficiencies. The exdmer-laser ablation of cornea in the form of Laser-Assisted in Situ Keratomileusis (LASIK) or Photorefractive keratectomy (PRK) are considered as kerato-refractional techniques of correction of presbyopia. The femtosecond laser intrastromal correction of presbyopia (INTRACOR) is also labeled as kerato-refractional technique of correction of presbyopia and it is based on making intrastromal concentric rings in the central optical zone of cornea. The deficiency of INTRACOR is a relatively high cost of procedure due to application of femtosecond laser. The implantation of inlays (artificial devices) into cornea permits correcting presbyopia with less financial expenses. However, there are number of contraindications for implementing. The Tornton and Schachar operations are referred to the group of sclerotic operations of correcting presbyopia. However, nowadays these interventions are practically out of application. The implantation of intraocular lenses, including accommodating, multi-focal and monofocal by the principle of monovision ones, can be considered as the most adequate mode of correction of presbyopia. The advantages and disadvantages of implantation of various types of intraocular lenses are considered in detail.
