Editing Cornea (section)

====Surgical procedures====

Various [[refractive eye surgery]] techniques change the shape of the cornea in order to reduce the need for corrective lenses or otherwise improve the refractive state of the eye. In many of the techniques used today, reshaping of the cornea is performed by photoablation using the [[excimer laser]].

There are also synthetic corneas (keratoprostheses) in development.  Most are merely plastic inserts, but there are also those composed of biocompatible synthetic materials that encourage tissue ingrowth into the synthetic cornea, thereby promoting biointegration. Other methods, such as magnetic deformable membranes<ref>{{cite journal |first1=Steven M. |last1=Jones |first2=Sandra E. |last2=Balderas-Mata |first3=Sylwia M. |last3=Maliszewska |first4=Scot S. |last4=Olivier |first5=John S. |last5=Werner |title=Performance of 97-elements ALPAO membrane magnetic deformable mirror in Adaptive Optics - Optical Coherence Tomography system for ''in vivo'' imaging of human retina |journal=Photonics Letters of Poland |volume=3 |issue=4 |year=2011 |pages=147–9 |url=http://photonics.pl/PLP/index.php/letters/article/view/3-52}}</ref> and optically coherent [[transcranial magnetic stimulation]] of the [[Retina|human retina]]<ref>{{cite book |doi=10.1109/IEMBS.2010.5627660 |pmid=21097016 |chapter=Towards direct head navigation for robot-guided Transcranial Magnetic Stimulation using 3D laserscans: Idea, setup and feasibility |title=2010 Annual International Conference of the IEEE Engineering in Medicine and Biology |volume=2010 |year=2010 |last1=Richter |first1=Lars |last2=Bruder |first2=Ralf |last3=Schlaefer |first3=Alexander |last4=Schweikard |first4=Achim |isbn=978-1-4244-4123-5 |pages=2283–86|s2cid=3092563 }}</ref> are still in very early stages of research.
