Abstract:
According to the anatomic classification,refractive surgery is divided into keratorefractive surgery,phakic refractive surgery and scleral refractive surgery.Most procedures for the correction of ametropia are performed on the cornea,with laser-assisted in situ keratomileusis(LASIK) being the most common one.LASIK has shown its limitations,however.For the correction of higher myopic and hyperopic refractive error,the procedure has considerable undesired effects,such as loss of contrast,glare,and iatrogenic keratectasia.Therefore,a variety of intraocular lens,known as phakic refractive surgery,have been designed to achieve full correction of high myopia and hyperopia without loss of accommodation.Phakic refractive surgery is different from kerato-or scleral refractive surgery in that it involves phakic intraocular lens,non-phakic intraocular lens and clear lens extraction +introcular lens.The author will outline recent progress in phakic intraocular lens and provide unifying concepts that are accepted by ophthalmologists.
