Glaucoma may not be an absolute contraindication to Laser-Assisted in situ Keratomileusis (LASIK), but so far it is a relative one. People who are glaucoma suspects or who have glaucoma are just as likely as any other to seek laser refractive surgery. LASIK is a popular ocular procedure, relatively pain free and it is carried out with an extremely precise computer-controlled excimer laser emission. On the other hand, glaucoma is a group of diseases manifested by optic nerve damage with visual field changes. Patients that undergo a transient but significant rise in intraocular pressure during LASIK procedure have risk of further optic nerve damage. Furthermore, steroids which are typically used after refractive surgery can increase intraocular pressure (IOP) especially in steroid responders, who are more prevalent among glaucoma patient. Glaucoma patients interested in LASIK surgery may visit a glaucoma specialist or another LASIK surgeon who has had experience with performing LASIK in glaucoma patients. PRK (photorefractive keratectomy), LASEK (laser epithelial keratomileusis) are good alternatives for glaucoma patients. Refractive surgeons might want to consider giving patients a photo of their optic nerve, or a drawing, or an objective record of their preoperative examination.
青光眼可能并非准分子原位角膜磨镶术(LASIK)的绝对禁忌证,但到目前为止它属于相对禁忌证。青光眼疑似患者或青光眼患者和其他任何人一样,都有可能寻求激光屈光手术。LASIK是一种常见的眼科手术,相对无痛,且通过极其精确的计算机控制准分子激光发射来进行。另一方面,青光眼是一组以视神经损伤伴视野改变为特征的疾病。在LASIK手术过程中眼压出现短暂但显著升高的患者有进一步视神经损伤的风险。此外,屈光手术后通常使用的类固醇药物会升高眼压,尤其是在类固醇反应者中,而这类人群在青光眼患者中更为常见。对LASIK手术感兴趣的青光眼患者可以咨询青光眼专科医生或另一位有对青光眼患者实施LASIK手术经验的LASIK外科医生。对于青光眼患者来说,准分子激光角膜切削术(PRK)、准分子激光上皮下角膜磨镶术(LASEK)是不错的选择。屈光手术医生可能会考虑给患者提供一张其视神经的照片、一幅图或术前检查的客观记录。
