Initial Clinical Evaluation of an Intraocular Femtosecond Laser in Cataract Surgery

Abstract

Initial results with an intraocular femtosecond laser demonstrate higher precision of capsulorrhexis and reduced phacoemulsification power in porcine and human eyes.

Correlation between anterior chamber characteristics and laser flare photometry immediately after femtosecond laser treatment before phacoemulsification

“…[1][2][3][4]6 Regarding safety features of the FLACS, studies have shown that the incidence of intraoperative complications such as suction breaks or anterior capsular tears decreased with experience and were o2%. 1-3 Macular thickness did not differ between FLACS and traditional phacoemulsification.…”

“…1-3 Macular thickness did not differ between FLACS and traditional phacoemulsification. [1][2][3] Additionally, the Femtosecond laser-assisted anterior capsulotomy was a safe procedure for postoperative posterior capsule opacification rates due to better intraocular lens position. 13 Table 1 Descriptive statistics (mean ± standard deviation, minimum, maximum, n = number) and P-value of different anterior chamber (AC) and cornea characteristics (AC depth, AC volume, AC angle, corneal thickness (CT), central corneal thickness (CCT), endothelial cell (CD)) in the complete study population according to three measuring times-preoperatively, 10 min post femtosecond laser treatment and 1 day follow up…”

“…[1][2][3][4] In addition, improved intraocular lens placement, capsule overlap, circularity of capsulotomy and centration of the intraocular lens were compared with manual procedures. [1][2][3][4] The corneal incision by the femtosecond laser was stable and did not significantly change the higher order aberrations. 5 Side effects including miosis, ocular inflammation, and alternated anterior chamber (AC) characteristics were experienced in few patients.…”

“…5 Side effects including miosis, ocular inflammation, and alternated anterior chamber (AC) characteristics were experienced in few patients. [1][2][3][4]6 Another study demonstrated the impact of different pulse energy levels on the tissue outcome after capsulorhexis performance. 6 A soft contact lens interface with a pulse energy of 5 μJ resulted in fewer tags and bridges, smoother edges, and a more regular and thinner demarcation line on specimen edges with the femtosecond laserperformed capsulotomies versus a rigid and curved 15 μJ interface application using light and scanning electron microscopy.…”

Cirurgia de catarata a laser

“…Ambrósio fez excelente revisão sobre este tipo de laser recentemente nesta revista (1) . A primeira facectomia em humanos assim realizada foi em 2008, na cidade de Budapeste (2) . Até o momento, já passam de dois mil casos operados em todo o mundo.…”
