Arcuate keratotomy infiltration following uneventful femtosecond laser assisted cataract surgery

“…Earlier in 2015, Chou et al from USA had reported a case of femtolaser LRI which showed infiltration due to methicillin-resistant Staphylococcus aureus after an uneventful FLACS. [2] Recently, in 2018, Grillo et al reported a case of late onset Microsporidial keratitis following an uneventful FLACS with femtosecond laser AK in the USA. [3] In India, Haripriya et al had reported a case of keratitis and a case of endophthalmitis following manual LRI in phacoemulsification.…”

“…Arcuate keratotomy (AK) is an efficacious intraoperative procedure for reduction of pre-existing corneal astigmatism between 0.5 and 3.0 D.[1] However, it may also act as an additional route of entry of micro-organisms, increasing the risk of post-operative infection. [234] The advent of femtosecond laser has made it possible to create highly accurate and well-structured AKs. We report first case of femtosecond laser AK infiltration from south-east Asia, and also propose recommendations for prevention and treatment of these cases.…”

Femtosecond Laser-Assisted Ophthalmic Surgery: From Laser Fundamentals to Clinical Applications

“…In FS-AK, the cornea wounds are closed, which can decrease the incidence of infection. However, any corneal incisions have the risk of complications including infection, inflammation, wound gaping, scarring, and unintended full thickness incisions [ 51 , 63 , 64 ]. In general, infection after FS-AK alone or FS-AK performed in combination with cataract surgery is rare.…”

“…In general, infection after FS-AK alone or FS-AK performed in combination with cataract surgery is rare. A few cases of keratitis after FS-AK were reported [ 63 , 65 , 66 ]. Thus, FS-AK is generally considered to be safe.…”

Femtosecond laser-assisted keratotomy

“…Infection after femtosecond laser-assisted astigmatic keratotomy Infection, although rare, has been reported after FSAK [30]. One patient developed a methicillin-resistant Staphlococcus aureus (MRSA) corneal infiltrate in one of two paired astigmatic keratotomy incisions 3 weeks after having femtosecond-enabled cataract surgery.…”
