Applications of femtosecond lasers in ophthalmic surgery.

PURPOSE: To review recent advancements in applications of the femtosecond (FS) laser in ophthalmology.

DESIGN

Literature review and commentary.

RESULTS

With the FS laser, it is now possible to produce a more precise flap diameter, hinge and depth of the flap in laser in situ keratomileusis surgery. Recently, the FS laser has been used for both flap creation and refractive correction by lenticule extraction. This laser can also be used for preparing host and donor tissue in different shapes so as to obtain faster recovery and improved postoperative visual acuity. Intracorneal ring segments for keratoconus and post-laser in situ keratomileusis ectasia can be placed using the FS laser. Higher precision of capsulorrhexis and lens softening is also achievable with FS laser-assisted cataract surgery.

CONCLUSION

Innovations focused on improving FS laser technology will continue and will lead to expanded applications of the FS laser in ocular surgery.
