有晶状体眼人工晶状体植入术治疗高度近视

从解剖部位上来分，屈光手术可以分为角膜屈光手术、晶状体屈光手术和巩膜屈光手术。许多矫正非正视眼的手术主要集中在角膜，如准分子激光角膜原位磨镶术（LASIK）。但其在矫正高度近视和远视时已经显示了它的局限性，如眩光、医源性角膜突出、屈光回退等。而晶状体屈光手术是区别于手术部位在角膜和巩膜上的一类手术，包括有晶状体眼的人工晶状体植入、无晶状体眼的人工晶状体植入以及透明晶状体摘除联合人工晶状体植入术。在此，作者对有晶状体眼的人工晶状体植入术作一综述，并提供一些目前较为一致的观点。

Phakic refractive surgery to cure high myopia

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.
