A refractive error is a very common eye disorder. It occurs when the eye cannot clearly focus on images. The result of refractive errors is blurred vision, which sometimes is so severe that it causes visual impairment.
The three most common refractive errors are
It transmits laser pulses at a considerably denser rate than other femtosecond laser equipment. For this reason, the energy used to make the flap as well as the spot size are significantly smaller than with other femtosecond-based lasers. Due to its low amount of energy, side effects and mechanical tensions on the cornea are as minimal as possible.
