The effect of astigmatic Holmium:YAG laser thermokeratoplasty in three eyes with previous surgery (extracapsular cataract extraction, penetrating keratoplasty and failed extracapsular cataract extractionntric photorefractive keratectomy 1 to 7 years previously) was evaluated. In the extracapsular cataract extraction eye the effect of a four-spot laser thermokeratoplasty regressed to almost zero within 1 week. In the penetrating keratoplasty and photorefractive keratectomy eyes an eight-spot laser thermokeratoplasty produced an enormous overshoot in astigmatic power of about 15.00 diopters (D), decreasing within 5 months to almost zero in the eye with penetrating keratoplasty and to 4.00 to 5.00 D corneal astigmatic power in the photorefractive keratectomy eye after 8 months of observation.
钇铝石榴石激光热角膜成形术对三只曾接受过手术（分别为囊外白内障摘除术、穿透性角膜移植术以及1至7年前失败的囊外白内障摘除联合准分子激光角膜切削术）的眼睛的效果。在接受囊外白内障摘除术的眼睛中，四点激光热角膜成形术的效果在1周内几乎消退至零。在穿透性角膜移植术和准分子激光角膜切削术的眼睛中，八点激光热角膜成形术导致散光度数大幅增加，约为15.00屈光度（D），在穿透性角膜移植术的眼睛中，5个月内降至几乎为零，在准分子激光角膜切削术的眼睛中，观察8个月后角膜散光度数降至4.00至5.00 D。
