TI  - Excimer laser photorefractive keratectomy for hyperopia.
PG  - 30-4
AB  - BACKGROUND AND OBJECTIVE: Photorefractive keratectomy (PRK) has been extensively 
      evaluated for the correction of myopia. This study was undertaken to assess the 
      safety, efficacy, and reliability of PRK in the correction of hyperopia. PATIENTS 
      AND METHODS: There were 28 eyes with refractions of +1 to +7.75 D treated for 
      hyperopia with the Chiron Technolas 217-C excimer laser. Thorough visual 
      assessments were made before treatment and at regular follow-up to 18 months. 
      Complications and patient satisfaction were noted. RESULTS: At 18 months the mean 
      subjective refraction was +0.46+/-1.00 D with 26 eyes (92.8%) within 1 D of 
      emmetropia. Thirteen eyes (46.4%) achieved uncorrected visual acuity (UCVA) of 
      20/20 or better and all patients had an UCVA of > or = 20/32 or better. Best 
      corrected visual acuity (BCVA) remained unchanged in 26 eyes (92.8%) and improved 
      in 2 eyes (7.2%). On the seventh day from treatment, 17 eyes (25%) had a loss of 
      2 or more lines of BCVA. At 15 days this was reduced to 8 eyes (14.3%) and at one 
      month to 3 eyes (3.6%). There were no cases of loss of 2 or more lines of BCVA at 
      18 months of follow-up. All patients expressed a high degree of satisfaction. 
      CONCLUSIONS: Photorefractive keratectomy safely and effectively reduced hyperopia 
      in the patients studied. The technique was reliable and still offered good 
      results at 18 months of follow-up.
