AB  - PURPOSE OF REVIEW: Ametropia and astigmatism following successful penetrating 
      keratoplasty can seriously impact a patient's quality of vision. Similar 
      limitations can result following anterior lamellar keratoplasty (ALK) and 
      Descemet's stripping endothelial keratoplasty (DSEK). These patients often suffer 
      from aniseikonia and can be intolerant of spectacles and contact lenses. 
      Refractive surgery can correct both ametropia and astigmatism following corneal 
      transplantation and improve a patient's final visual outcome. The same methods 
      used to correct naturally occurring refractive errors are being used with 
      increasing success in patients who have undergone corneal transplants. RECENT 
      FINDINGS: Many refractive options are available to treat ametropia following 
      penetrating keratoplasty. Incisional keratotomies have been employed to treat 
      high amounts of astigmatism. Photorefractive keratectomy (PRK) and laser in-situ 
      keratomileusis (LASIK) are also used to treat myopia, hyperopia and astigmatism. 
      LASIK has been shown to have an overall better outcome compared to PRK; however, 
      the use of mitomycin-C with PRK has improved results. Phakic and pseudophakic 
      piggyback intraocular lenses are also being used to treat high degrees of 
      ametropia and astigmatism; however, the long-term results are somewhat limited. 
      SUMMARY: Refractive surgery can improve the final visual outcome of patients who 
      have undergone successful corneal transplantation. Currently available modalities 
      provide many options for patients who are intolerant of spectacles and contact 
      lenses. Continued advances and research will enable surgeons to optimize visual 
      quality in postkeratoplasty patients.
