Ophthalmic surgical laser and method

摘要: Low energy, ultra-short (femptosecond) pulsed laser radiation is applied to the patient's eye in one of a number patterns such that exposed ocular tissue ablated or excised through process optical breakdown photodisruption very controlled fashion. The can be gentle enough invention makes possible performance surgical procedures past could not have been performed at all, as capsulorhexis, were fashion provided less than an ideal result excessive trauma tissue. Such latter applications include making incisions for corneal transplantation, radial and arcuate keratotomy, intrastromal cavitation. Using inside allows surgeon perform glaucoma operations trabeculoplasty iridotomy, cataract techniques capsulectomy, capsulorhexis phacoablation, vitreoretinal surgery, membrane resection. various are accomplished by controlling energy flux irradiance, geometric deposition beam exposure time.
