    Optic Neuropathy Associated With Laser In Situ Keratomileusis 

    J Cataract Refract Surg 26: 1581-1584, 2000

        


    Intraocular pressure (IOP) may rise significantly during the lamellar cut portion of LASIK. The authors report 4 cases of optic neuropathy after LASIK. 

         


    During the lamellar cut portion of LASIK, a suction device is applied to stabilize the globe and increase IOP to achieve a smooth cut.

         


    In the vacuum phase, IOP can increase to 80 to 230 mm Hg with a microkeratome. During the lamellar cut IOP can reach 140 to 360 mm Hg.

        


    In the above 4 cases, 2 developed retrobulbar optic neuropathy while 2 developed anterior ischemic optic neuropathy.

        


    The resulting visual acuity and field loss were permanent.
