This relatively noninvasive method of optical cor- rection also avoided the healing problems of graft failure/ rejection and frequent follow-up visits. In cases with irregular corneal surface due to chemical injury, it is important to perform manual ultrasonic pachyme- try prior to surgery to confirm Orbscan readings, which can be inaccurate when corneal opacities are present. Additionally, these cases should be carefully followed up, as corneal neo- vascularization and stromal inflammation or melting can be stimulated by ICRS implantation even in normal eyes, and might be more likely in an eye with lasting damage from a chemical burn, even when the segments are placed away from the area of most severely injured cornea. In conclusion, ICRS implantation might be an option for the management of corneal irregularities secondary to ocular surface problems, if special consideration is given and required preventive measures are taken according to the thickness of the cornea in the region of the femtosecond laser beam.
