Using the new excimer laser photorefractive keratectomy ( prk ) , the molecular bond of the corneal stroma is broken to allow recofiguration of the cornealsurface . this photo - ablation effect can treat severe myopia , astigmatism , and a variety of corneal diseases using photo - therapeutic keratectomy ( ptk ) . the safety , predictability , and long - term stability are well established in major western medical facilities 準分子激光技術在國內、外安全使用十一年,并得到眾多醫學權威機構的認定,具有安全性及精確度高、可預測性強、長期穩定性好的特點,我院已為幾百名近視患者實施了這種手術, 90的患者術后視力達到1 . 0以上。

There are many options for the correction of refractive errors today and these include the use of the excimer laser platform - like photorefractive keratectomy ( prk ) , laser in situ keratomileusis ( lasik ) , laser subepithelial keratomileusis ( lasek ) , and epilasik ; and those that require the placement of an intraocular lens inside the eye . each procedure , however , has pros and cons and the best procedure for a patient is ideally decided after a detailed examination of the eye by the surgeon 時至今日,用以矯正屈光不正的方法有很多種,包括:準分子激光技術例如激光屈光角膜切除術( photorefractivekeratectomy - prk ) 、角膜激光矯視手術( laserinsitukeratomileusis - lasik ) 、角膜上皮切割激光矯視手術( lasersubepithelialkeratomileusis - lasek ) 、 epilasik及人工晶體植入等等。每種手術皆有其利弊,病人宜先接受詳細眼科檢查,再由醫生建議合適的手術。

Conjunctival transplantation after keratectomy has been very successful in unilateral chemical and thermal injury . 8 months follow - up of 11 unilateral burn patients treated by conjunctival transplantation shows : 11 are stabilized of the ocular surface , 9 improved vision , 2 healed epithelial defect , 2 released symblepharon 摘要經化學或熱灼傷之病人其眼部表面受到傷害,常會有角膜表皮愈合不良,纖維血管增生而致表面不規則,角膜混濁等并發癥。

Methods : we examined 102 patients who underwent photorefractive keratectomy and received topical steroids ( either fluorometholone 0 . 1 % or prednisolone acetate 0 . 5 % alone or combined ) as part of postoperative therapy 方法:我們檢查了103名已行屈光性角膜切除術并以局部類固醇( 0 . 1丙酮縮氟氫羥龍或0 . 5潑尼松龍或二者兼有)作為部分術后治療的病人。

Radial keratotomy ( rk ) and photorefractive keratectomy ( prk ) are other refractive surgeries used to reshape the cornea 其他用于角膜重新塑形的外科手術還有放射狀角膜切開術( rk )和光性折射角膜切削術( prk ) 。
