Application Of Femtosecond Assisted Cataract Surgery In Black Nucleus

Purpose:
To investigate the efficacy and safety of femtosecond laser assisted cataract surgery (FLACS) in black nucleus cataract surgery.

Because of the high hardness of the nucleus and the difficulty of the operation, the complications of conventional phacoemulsification (CPS) are easy to occur. Femtosecond laser assisted technology can accurately complete capsular tearing, pre-nucleus splitting and incision making, which is expected to improve surgical safety, reduce complications and improve postoperative results. The purpose of this study was to evaluate the application of FLACS in black nucleus cataract surgery.

Femtosecond laser-assisted cataract surgery (FLACS) was performed in 135 patients (139 eyes) with black nucleus cataract (61~86 years old) in Ideal Eye Hospital Affiliated to Soozhou University from 2016 to 2022. The LenSX femtosecond laser completes the capsular tearing, nucleus cleft and incision, followed by phacoemulsification implantation into the flat loop intraocular lens (IOL), removal of viscoelastic, watertight incision, and application of tobramycin and dexamethasone ophthalmic ointment to the conjunctival capsule. With the exception of the laser procedure, the procedure was performed by the same skilled physician, the same as conventional phacoemulsification (CPS).

139 eyes completed complete laser capsulorhexis. All patients successfully completed phacoemulsification without posterior capsule rupture and other complications. Corneal edema is light and postoperative recovery is fast.Femtosecond laser-assisted precleavage system can cut the hard nucleus into honeycomb small pieces, which can reduce the damage of intraocular tissue. It is significant to reduce the complications of hardcore cataract surgery.

femtosecond laser assisted black nucleus cataract incision was successfully made. The capsular tear condition is good, the recovery after laser presplitting is fast and the complications are few.
