title: Silicone intraocular lens compression and double lens implants in diseased eyes.
abstract: OBJECTIVE
  To assess the outcomes of double lens implants in hyperoptic eyes with associated pathology.
  
  
  METHODS
  Double lens implants were used in 4 eyes of 4 patients each with a different ophthalmic or neuro-ophthalmic disease. Biometry was performed in the standard contact fashion and lens power formulae used included SRK/T, Holladay and Hoffer Q.
  
  
  RESULTS
  Average spherical equivalent refraction improved from +6.875 D to +0.38 D. Absolute average prediction error was greatest for SRK/T (2.65 D) and least for Holladay (1.73 D). Refractive suprises were influenced by the underlying disease process. One patient showed central lens compression.
  
  
  CONCLUSIONS
  Underlying disease can produce biometry errors. Structural ophthalmic or neurological disease is not a contraindication to the use of double lens implants. Double lens implants are useful to correct refractive error in the presence of underlying disease.
