“…We also noticed that the BSS was greater in the FLACS group; however, this difference did not reach the threshold of statistical significance. Research has suggested that FLACS can effectively reduce EPT and CDE, properties related to the laser-assisted fragmentation and softening of the lens [32]. In our investigation, we specifically excluded patients with moderate to severe cataract and scans signal strength index of < 50 to acquire high-quality image; this may be why we did not observe differences in CDE and EPT between the groups in our study.…”

Purpose: To assess differences in post-surgical radial peripapillary capillary (RPC) density changes between femtosecond laser-assisted cataract surgery (FLACS) and conventional phacoemulsification surgery (CPS) using optical coherence tomography angiography (OCTA).Methods: Fifty-two eyes of 52 patients were enrolled in this study. Depending on their preference, patients with age-related cataract underwent FLACS or CPS. Automated peripapillary maps and capillary density calculations were retrospectively evaluated using OCTA before surgery and on day 1 and months 1 and 3 postoperatively.Results: The whole-image and peripapillary RPC densities were lower at day 1 and months 1 and 3 postoperatively than before surgery in the FLACS group (all P < 0.05). However, there was no change in the whole-image and peripapillary RPC densities before and after surgery, across different time-points, in the CPS group (all P > 0.05). Moreover, comparison of data corresponding to each time-point between the FLACS and CPS groups showed no significant differences in any metrics prior to surgery (all P > 0.05). However, the whole-image and peripapillary RPC densities were significantly different at day 1 and month 1 after the surgery (all P < 0.05). At the 3-month follow-up, we did not observe significant differences (all P > 0.05). Conclusions: Postoperative whole-image and peripapillary RPC densities were lower in the FLACS group than in the CPS across time-points. While the short-term RPC density changes were resolved, to elucidate the long-term implications of FLACS, especially for eyes with glaucoma, diabetic retinopathy, etc., further investigations are required.

“…FLACS can provide better precision and predictability over manual phacoemulsification, 8 especially in challenging cases with a shallow anterior chamber, subluxated cataracts, or an iris coloboma with a narrow pupil in a microphthalmic eye, as in our case. 9 On the other hand, it requires more time and costs more. Also, it may induce miosis and a weaker capsulorhexis compared to manual capsulorhexis.…”

This paper reports the technique and outcome of femtosecond laser-assisted cataract surgery (FLACS) in an iris coloboma patient (59-year-old male patient) with bilateral grade 3 cataractous lens and a shallow anterior chamber. Best-corrected visual acuity (BCVA) was 0 on logMAR with spherical equivalent (SE) 9 D in the right eye, and BCVA of 0.3 logMAR with a SE 8.75 D in the left. FLACS was performed on the left then the right eye using the Catalys platform of Johnson & Johnson (intraocular lens implantation of AMO Tecnis 1 ZCB00). Customized parameters were constructed to create capsulotomies of 4.54.7 mm for the left and right eyes, respectively, with manual centration of the distorted pupils. On the second day of follow-up, left-eye BCVA was 0.5 with SE 1 D, and right-eye BCVA was 1 with SE −0.75 D. At the 1-year follow-up, eyes showed stable bilateral Tecnis 1 IOL and refraction. FLACS is a safe surgical option with stable outcomes in cases of cataract with iris coloboma.

“…The advent of FLACS has provided cataract patients and surgeons with several benefits, especially in challenging cases. [8][9][10][11][12] Crema et al reported FLACS to be effective in patients with weak zonular and even lens subluxation and useful in preventing further zonular damage. 8 Vasavada et al concluded that compared to conventional phacoemulsification, FLACS showed a lesser decrease in endothelial cell density, less inflammation, and better vision in the early postoperative period in patients with a shallow anterior chamber.…”

“…8 Vasavada et al concluded that compared to conventional phacoemulsification, FLACS showed a lesser decrease in endothelial cell density, less inflammation, and better vision in the early postoperative period in patients with a shallow anterior chamber. 9 Additionally, compared with conventional phacoemulsification, FLACS has an advantage in managing hard nuclear and white cataracts. 10,11 Furthermore, in unusual cataracts, such as posterior polar cataracts, FLACS has shown enhanced safety.…”
