Visual Outcome in High Myopia After Laser in situ Keratomileusis. 
The aim of the study was to study the results of LaAIK for myopia over -12.00 D. Surgery was done using Hansatome microkeratome and Nidek EC-5000 excimer laser.  One hundred forty-five eyes were followed for a minimum of 6 months to assess the extent of correction and the gain or loss of lines as compared of previous spectacle correction.  Forty percent of eyes gained at least one line, 56% remained the same, and 4% lost one line of visual acuity.  Thirty-five eyes were undercorrected with the majority between 0 and -5.00 D. One hundred ten eyes achieved their preoperative best spectacle-corrected visual acuity with no correction.  Complications were minimal.  LASIK with the Nidek EC-5000 excimer laser achieved good results in eyes with myopia over -12.00 D. [J Refract Surg 2000; 16(suppl):S247-S250].
