eview articlePost-operative clinical examinationPost-operative clinical examination should includerefraction, routine slitlamp examination with measurementof intraocular pressure and funduscopy with dilatedpupils, measurement of the endothelial cell count,and Scheimpflug imaging. Since the anterior chamberchanges with age, Scheimpflug imaging should be performedevery year to document the position of the IOLin the eye and also the anterior chamber depth. This isespecially important in hyperopic patients. As describedabove, significant loss of corneal endothelium is a seriouscomplication after phakic IOL implantation and theIOL should be removed [ 7 ].ConclusionThere has been a great progress in designs and materialsof phakic IOLs within the last 20 years. Two differentkinds of phakic IOLs are FDA approved at the momentand have shown excellent results within the last 10–15years. The iris-claw lens originally invented by Fechnerand Worst and the posterior chamber phakic IOL named‘ICL’. However, FDA approval is only for the treatment ofmyopic patients at the moment. Clinical trials for FDAapproval with toric IOLs are ongoing. The lenses are notyet approved for the implantation in hyperopic patients.Almost all angle supported phakic IOLs have beenabandoned from the market few years after introduction,so far. Alcon has recently introduced a new foldableangle supported phakic IOL made of hydrophobic acrylicmaterial (Cachet, Alcon, USA). Since the maximumfollow-up time with this IOL is only 3 years, refractivesurgeons should be cautious with this IOL, until longerfollow-up periods are published. Many angle-supportedphakic IOLs have shown good results within the first 3years after implantation and had to be abandoned afterwardsdue to serious complications [ 4 ].Financial disclosureThe authors have no financial interest in any techniqueor product mentioned in this manuscript.Conflict of interestTh e authors declare that there are no actual or potentialconflicts of interest in relation to this article.References1.
