LASIK is the most common refractive surgery performed worldwide. Some patients, however, are not suitable candidates for excimer laser refractive surgery due to high refractive error, issues with pupil diameter, corneal thickness or questionable corneal biomechanics. There are also some concerns regarding quality of vision and contrast sensitivity when very high refractive errors are corrected using excimer laser.
Phakic IOLs, which entered the market in the 1980s, did not incite significant interest due to the complications associated with the initial versions of the lenses and the success of the excimer laser. It was only in the late 1990s and early 2000s that there was a resurgence of interest in phakic IOLs, with the Verisyse/Artisan (Abbott Medical Optics/Ophtec) and the ICL (STAAR Surgical) being the two most commonly used designs. Angle-supported phakic IOLs are no longer used, with the latest design, the Alcon Cachet, withdrawn from the market over concerns regarding endothelial damage.
