Cataract surgery. Left eye worsens. Laser surgery. Eye worsened. Laser again unable to see out if that eye but blurred vision. Not supposed to have to wear glasses was told. They gave me a prescription and unable to see at all. Went for second opinion and was told prescription is not right and should never have had the lasik surgery which caused more damage. Now they took my money for the glasses from my ins and won’t give me a pair of glasses. $4000.00 later blurred vision and no glasses.
