Abstract
To study the review of literatures about the use of phakic intraocular lenses (IOLs) in correction of high myopia, efficacy, advantages, disadvantages, possible early and late complications and its comparison with other methods of myopic correction.
Conclusion
Surgical correction for high myopia is proposed in cases who can not tolerate contact lenses or glasses. There are several surgical techniques for the correction of myopia which include; radial keratotomy (RK), photorefractive keratectomy (PRK), automated lamellar keratoplasty (ALK), and laser-in situ keratomileusis (LASIK). Theses procedures are all performed by altering corneal tissues. The treatment of higher amounts of myopia using corneal surgery is more controversial with LASIK, showing the greatest promise. However, large, ablation depths, smaller diameter ablation zones, increased optical aberrations, and poorer predictability have raised doubts that the cornea is the appropriate site for the correction of high to extreme refractive errors. The surgical correction of myopia with an intraocular lens (IOL) implanted in the phakic eye has been a controversial issue in the past decades. Despite previous controversies, this procedure offers well defined advantages as a refractive surgical technique because of its simplicity, potential reversibility, precision and the stability of the refractive correction achieved. The advantages of phikic intraocular lens are more evident in high myopic correction, in which excimer laser corrections have more limitations and are hampered by problems in night vision, regression and poor optical quality of the reshaped cornea. The modern phakic intraocular lens has the benefit of the latest technological developments in lens design and industrial production. However, currently limited data are still available concerning the long term follow up of eyes implanted with phakic intraocular lens. Thec potential complications for eyes implanted with PIOL must be clarified before these lenses are widely used in refractive surgery.
