title: Retinal Imaging through Phakic Iris-Claw IOL.
abstract: BACKGROUND
  Phakic anterior chamber iris-fixated IOL (PIOL) are established for the correction of high myopia. These patients require attention to macular pathologies. This study was to evaluate the quality of imaging through the PIOLs.
  
  
  METHODS
  54 eyes of 31 myopic and hyperopic patients with Verisyse, Verisyse toric, and Veriflex phakic iris-fixated IOL were included. Mean preoperative refraction was -11.0 D and +5.7 D, respectively; mean follow-up time was 7.4 years (5-11 years). A matched control group was formed without PIOL implantation. OCT scans were performed and evaluated qualitatively and quantitatively.
  
  
  RESULTS
  In 52 eyes of 31 patients (96%), a 3D-OCT image and fundus photo could be obtained in good quality. Foveal thickness was significantly thicker in the myopic patients, whereas all other sectors and total volume had no significant difference.
  
  
  CONCLUSIONS
  It proved possible to obtain high-resolution scans and digital photos of the same quality as without additional phakic IOL.
