“…Although the results did not reach statistical significance, Seidel testing showed that the mean IOP at which leakage occurred was higher for the FS laser, indicating sealability to be better with the FS laser-generated CCI. As discussed in the recent review by Nagy and McAlinden, 24 FS lasers deliver consistent and precise multiplanar incisions, which are an integral part of securely controlling the avenue where infectious materials are less likely to navigate. At low IOP levels, wounds created by manual corneal incisions could become unstable, potentially risking entry of bacteria.…”

The FS laser-created incisions corresponded well with the treatment plans, as evidenced by true multiplanar architecture. Incisions were sharply demarcated and demonstrated limited cell damage. No postprocedure leaking at extreme IOP or postcataract surgery-simulated conditions was noted. The FS laser may potentially reduce postoperative complications, such as infections that may be associated with CCI.

“…Recently a femtosecond laser (FSL) has been introduced into phacoemulsification cataract surgery to open the lens capsule, fragment the cataract, and make corneal incisions, with corneal scarring being the only absolute contraindication for its use. 27 FSL-assisted cataract surgery, compared to the conventional technique, requires less phacoemulsification energy and time, which may reduce the thermal injury to ocular tissues by ultrasound and corneal edema. 27 , 28 Greater precision in stages of cataract surgery performed with FSL is suggested to improve visual and refractive outcomes in the short term.…”

Extending life expectancy is a human achievement. It does however entail problems. Ophthalmic treatments are widely recognized as having a low risk of general complications. A classic example is cataract surgery, considered to be one of the safest and most frequently performed surgical procedures in the world. However, advanced age brings with it risks that should be considered before surgery. Eye operations, as with procedures on other organs, are largely dependent on the quality of surgical tissues. Therefore, the elderly are at increased risk of complications. Improved general health and postoperative follow-up with the use of noninvasive technologies such as optical coherence tomography translate into lower intraoperative risk and better postoperative prognosis. In this review, we discuss the impact of general health on operational prognosis, therapeutic problems, and technical difficulties which a surgeon and anesthesiologist may encounter in the process. We also consider new technology and strategies specifically aimed at treating eye conditions in the elderly.

“…The use of femtosecond laser in cataract surgery has become a common practice in cataract surgery to perform several steps of the surgical procedure: anterior capsulotomy, lens segmentation, and creation of corneal incisions [1]. It has been demonstrated that femtosecond lasers are able to generate clear corneal incisions (CCI) with minimal associated changes of anterior and posterior corneal topography, and comparable with those of single-plane angled manual incision [2] [3].…”

Purpose: To investigate the efficacy of non-penetrating femtosecond laser intrastromal astigmatic keratotomy (ISAK) in terms of topographic and refractive changes. Methods: Retrospective study including 42 eyes (35 patients) with a corneal astigmatism between 0.5 and 1.5 D. All eyes underwent femtosecond laser-assisted cataract surgery with ISAK for astigmatism management using the Catalys laser system (Johnson & Johnson Vision). Visual acuity, refraction, as well as corneal topographic and corneal endothelial cell density (ECD) changes were evaluated during a 12-month follow-up. Astigmatic changes were analyzed using the Alpins vector method. Results: A significant reduction in manifest cylinder was observed at 1 month postoperatively (p = 0.03), with no significant changes afterwards (p = 0.90). A total of 38.1%, 52.4% and 59.2% of eyes had a manifest cylinder of 0.50 D or lower preoperatively and at 1 and 12 months after surgery, respectively. A significant reduction was found in topographic astigmatism at 1 month postoperatively (p < 0.01), with an additionally small but statistically significant reduction afterwards (p < 0.01). No significant changes in postoperative uncorrected (p = 0.97) and corrected visual acuities (p = 0.40) were observed during the follow-up. There was a trend to undercorrection of corneal astigmatism that decreased significantly over time. This led to some variability in changes of refractive astigmatism. A small but significant reduction in ECD was observed at 1 month postoperatively (p < 0.01), with no significant changes afterwards. Conclusions: Femtosecond laser assisted ISAK is an effective and safe option to reduce corneal astigmatism during cataract surgery and consequently refractive astigmatism.
