Advances in femtosecond laser technology

Abstract

Femtosecond laser technology has become widely adopted by ophthalmic surgeons. The purpose of this study is to discuss applications and advantages of femtosecond lasers over traditional manual techniques, and related unique complications in cataract surgery and corneal refractive surgical procedures, including: LASIK flap creation, intracorneal ring segment implantation, presbyopic treatments, keratoplasty, astigmatic keratotomy, and intrastromal lenticule procedures.

Femtoszekundumlézeres keratoplasztika

“…A femtoszekundumlézert a szemészetben eredetileg refraktív célból kezdték alkalmazni, de segítségével számos, tetszőleges metszési forma kialakítható, ezért felhasználási területe hamar kiszélesedett [6][7][8].…”

“…A femtoszekundumlézerek szemészeti alkalmazási területe folyamatosan bővül. A fő felhasználási terület a már említett femto-LASIK, de ezenkívül használható myopia, hypermetropia, astigmia, presbyopia kezelésére, stromalisalagút-seb készítésére intracornealis gyűrű beültetéséhez, továbbá lamelláris és perforáló szaruhártyaátültetésekhez [6][7][8]. Újdonságnak számít a myopia se-bészi kezelésében a lebenykészítés nélküli beavatkozás VisuMax készülékkel (Carl Zeiss Meditec AG, Jéna, Németország), stromalis lenticula eltávolításával [6,9,10].…”

Comparative study of femtosecond laser‐assisted cataract surgery and conventional phacoemulsification in vitrectomized eyes

“…The femtosecond laser was first introduced to ophthalmic care in 2008 . It has had an ever increasing role in cataract and refractive surgery by providing automation of formation of corneal incisions and flaps, continuous curvilinear capsulotomy and lens fragmentation, resulting in overall decreased phacoemulsification time and energy . Potentially, this might prove advantageous for post‐vitrectomy eyes, which are associated with higher reported complication rates due to fluctuating anterior chamber depth, weakened zonules, loss of vitreous support and an excessively mobile posterior capsule …”

“…3 It has had an ever increasing role in cataract and refractive surgery by providing automation of formation of corneal incisions and flaps, continuous curvilinear capsulotomy and lens fragmentation, resulting in overall decreased phacoemulsification time and energy. [3][4][5] Potentially, this might prove advantageous for post-vitrectomy eyes, which are associated with higher reported complication rates due to fluctuating anterior chamber depth, weakened zonules, loss of vitreous support and an excessively mobile posterior capsule. 6 The advantages of femtosecond laser-assisted cataract surgery (FLACS) might also be applicable to vitrectomized eyes developing sight-threatening cataracts but there appears to be a paucity of evidence to support this in existing literature.…”

Satisfaction of patients after advanced mono-refractive surgery

“…(6) LASIK is the most performed refractive surgery for the correction of myopia, hyperopia and astigmatism, and the use of femtosecond laser in refractive surgery has brought greater accuracy, safety and predictability of the procedure. (6)(7)(8) Unlike the use of a blade in the microkeratome, the femtosecond laser makes the flap by means of photodisruption, which forms cavitation bubbles composed of carbon dioxide and water in the planned cleavage plan. (9) The devices available on the market are considered safe, and they can be used in a predictable way to make the flap.…”
