    Implantable Contact Lens for Moderate to High Myopia: Phase
    – FDA Clinical Study with 6 Month Follow-up. 

    J Cataract Refract Surg 24: 607-611, 1998.

        


    There were about 400 cases of implantable contact lens (ICL) implantation worldwide, at the end of 1996. 

        

    The six month outcome of the first ten patients with ICLs implanted for myopia in the United States was excellent.

    Topiramate-Induced Acute Myopia and Retinal Striae

    Arch.Ophthalmol. vol.119, May 2001, pg. 775-777

       

    The causative mechanism of drug induced myopia has never been fully illustrated.



    The authors report an unusual case of acute myopia induced by topiramate (a new antiepileptic drug) in a 15-year old boy with epilepsy.



    The patient complained of sudden decrease in distance vision (in both eyes), with preservation of near vision, during a span of 24 hrs. A dilated fundus examination showed bilateral retinal striae radiating from the fovea (worse in left eye). Cycloplegic refraction was -7D in either eye.



    On cessation of topiramate (within 24 hours) vision gradually improved to 20/20 – at one week follow up and fundus examination was normal.



    The authors postulate the mechanism of action of topiramate, to a disturbance of the osmotic state of the lens and alteration of the refractive index.
