APPARATUS FOR OPHTHALMOLOGIC SURGICAL PROCEDURES USING A FEMTOSECOND FIBER LASER |
摘要 |
<p>Apparatus and method to generate a stream of pulses having a pulse repetition rate of at least about 50000 pulses per second and a per-pulse length of less than one picosecond, and to scan and focus the stream to an output light pattern suitable to sculpt tissue for a surgical procedure (e.g., ophthalmologic) using at least a high number of pulses to complete the operation in a matter of a few seconds, e.g., 100000 pulses in less than ten seconds. Some embodiments create a preconditioning negative dispersion that compensates for positive dispersion in the scanning system, in some embodiments; a lenticule is cut using the laser and scanning system and is mechanically removed through a side slit formed through the cornea surface.</p> |
