“…Fortunately, the pupil was well-dilated during the operation in this case after application of topical tropicamide and phenylephrine. It has been reported that pre-operative use of NSAIDs, shorter time lapse between laser application and phacoemulsification can reduce the chance of FLACS-related miosis [10,11]. With the assistance of a pupil-expanding device, FLACS can also be performed in small-pupil eyes [11].…”

Background: Femtosecond laser-assisted cataract surgery (FLACS) has been reported to reduce phacoemulsification time and energy compared to the manual phacoemulsification technique. This technique has been used in several complex cases such as zonular weakness, subluxated lens and traumatic cataracts because it causes less damage to weakened zonules. However, corneal opacity is considered a relative contraindication to FLACS, as it may interfere with laser beam delivery, thus causing unpredictable capsulorhexis and lens fragmentation/liquefaction. Case presentation: We present here a case with traumatic cataract and corneal opacity after laser-assisted in situ keratomileusis (LASIK). The patient was successfully treated using FLACS, capsular tension ring and intraocular lens (IOL) implantation. Posterior capsule rupture and vitreous loss were noted during the operation. However, the intraocular lens was successfully captured because of a complete capsulorhexis performed by FLACS. Conclusion: This case report demonstrates that FLACS is a useful tool in selected patients with concurrent corneal opacity and traumatic cataract.

“…For patients with small pupils, the decrease in overall surgical time reduces the release of inflammatory cytokines. 14 Previous studies have reported an association between IFIS and the intake of α-blockers (tamsulosin), which are commonly used for the treatment of benign prostatic hyperplasia and hypertension; the drugs are also risk factors for IFIS. 5 The Malyugin ring is the preferred pupil-expanding device for small pupils and is used instead of iris hooks in FLACS.…”

“…The new femtosecond laser model, Femto LDV Z8 (Ziemer; Port, Switzerland), is mobile and can hence be placed next to the operating microscope and the phacoemulsification device; the femtosecond laser procedures can be performed on the same surgical table as the cataract surgeries without the need for patient transfer. 14 The device is also capable of performing the FSAK, which offers superior incisional accuracy and reproducibility, and its unique low pulse energy ensures minimal effects on the collateral tissues. This technique obviates the insertion of a toric lens and can thus be considered a safer and more economical means for the correction of low-tomoderate corneal astigmatism.…”

The purpose of this study was to evaluate the efficacy of a novel double-docking technique, incorporating the use of femtosecond laser arcuate keratotomy (FSAK) in correcting lowdegree astigmatism and Malyugin ring, in a patient with intraoperative floppy iris syndrome (IFIS). Methods: A case report of a 72-year-old man with grade 4 cataract, low-degree astigmatism (<2D), and IFIS (pupil size <4 mm, intraoperatively) is presented. The patient underwent cataract surgery using a femtosecond laser to treat low-degree astigmatism because the patient requested for the use of a multifocal intraocular lens (IOL). The first docking was performed to complete arcuate keratotomy, produce the mainparacentesis incisions, and create clear corneal incisions. Insertion of the Malyugin ring was performed after the first docking, whereas the second one was executed to complete continuous curvilinear capsulotomy and lens fragmentation. The patient's uncorrected visual acuity (UCVA) was measured pre-and post-operatively. The complications were evaluated post-operatively and 3 months later during the follow-up visit. Results: The patient's UCVA for distance improved from 0.3 (6/12 Snellen equivalent) to 0 (6/6 Snellen equivalent) logMAR post-operatively. During the follow-up visit, the patient's uncorrected near visual acuity was at J2. His corneal astigmatism changed from −1.0 Diopter @177°pre-operative to −0.12 D @173°post-operative. No other intraoperative or postoperative complications were observed. Conclusion: The double-docking technique, with the use of FSAK, and Malyugin ring produced successful surgical outcomes for the patient. The benefits of this technique allow surgeons to avoid changing the shape of the patient's cornea from the injection of the viscoelastic device into the anterior chamber, which could lower the femtosecond laser's precision and docking location.
