“…This may be attributed to the relatively high incidence of posterior wound gape, in which the posterior wound margins were still separated. A high incidence of posterior wound retraction in the femtosecond group may indicate remodeling of the CCI resulting from endothelial cell necrosis, molecular dissociation, and biomechanical and thermal changes from the femtosecond laser [28]. A previous study, using transmission electron microscopy confirmed the difference between femtosecond laser corneal flap formation (necrotic keratocytes) and microkeratome corneal flap formation (keratocyte apoptosis), which may potentially explain the different incidence of posterior wound retraction in this study [29].…”

Optical coherence tomography (OCT), especially anterior segment OCT (AS-OCT), plays an important role in ophthalmology. With the technology evolving from time-domain to spectral-domain, more and more detailed ocular information has become available. Anterior segment OCT provides particularly useful information for cataract surgeons. This chapter focuses mainly on AS-OCT evaluation of eyes before and after cataract surgery. Four aspects including: (1) anterior lens capsule and lens epithelium evaluation using spectral-domain OCT (SD-OCT); (2) investigation of clear corneal incision in femtosecond laser assisted cataract surgery using SD-OCT; (3) capsular block syndrome evaluation before and after treatment using SD-OCT; (4) IOL power calculation in postmyopic excimer laser eyes using SD-OCT, will be discussed in this chapter.

“…High magnification light microscopy revealed complete cuts through several corneal layers with only minimal tissue bridges left in place. 154 This suggests that following corneal incisions created with the femtosecond laser, the eye must be considered "open". We therefore strongly recommend doing laser treatment and the other steps of the procedure in one room and expect that to become the standard of care for patient safety.…”

Purpose:We present the visual outcomes 6 weeks following Femtosecond laser assisted cataract surgery (FLACS) and conventional phacoemulsification cataract extraction (CE) cataract surgeries in 2013.Materials and Methods:This was a review of health record type of study. Eyes operated by FLACS and an equal number of conventional phacoemulsification (CE) on the same day by same surgeon were included in the study. Demographics, preoperative status, operative details and the best-corrected visual acuity (BCVA) at 6–8 weeks following surgery were noted. BCVA of >20/60 was considered as excellent. The rate and determinants of excellent vision were calculated.Result:Study population comprised of 154 eyes. Both FLACS and CL groups had 77 eyes. Visual acuity at 6–8 weeks was excellent in 44 (60%) eyes of FLACS group and 36 (40%) eyes of CE. Visual outcome following FLACS and conventional surgery was not different (Odd's ratio [OR] 1.5 [95% confidence intervals [CI]: 0.8–2.9]). Operating surgeon did not significantly influence the visual outcomes following FLACS (OR = 1.6) and CE (OR = 0.4). Association of the grade of lens opacities to the visual outcome was not affected by type of surgery (χ2 = 0.5, P = 0.2). The duration of surgery in CE and FLACS groups was not significantly different (−3.2 min [95% CI: −13; 6.6]).Conclusion:Visual outcomes at 6–8 weeks following CE were not different from FLACS. Visual outcomes following FLACS and CE were not influenced by the operating surgeon or severity of the cataract. The time required for FLACS was greater than that required for CE.
