steps in femtosecond laser cataract
Although the steps for each laser platform vary, they all need pupillary dilatation and topical
anesthesia, followed by applanation of the cornea with a docking system that includes a contact
lens with a circumferential suction skirt distributing pressure equally on the cornea. The docking
system minimally distorts anatomy while enhancing intraocular pressure (IOP), although
reportedly less IOP increase than seen in FSL refractive surgery. According to Friedman et al.,
the OptiMedica platform has a liquid optics user interface which enhances IOP by 15 mmHg and
avoids corneal folds.
Laser Cataract Surgery
Other platforms have actually not specified a degree of IOP boost. As soon as docking is
complete, anterior segment imaging is then carried out. LenSx and OptiMedica utilize Fourierdomain optical coherence tomography (FD-OCT), while LensAR makes use of Scheimpflug
imaging innovation. This step is needed to find anatomical landmarks for laser pattern mapping. It
is likewise essential that certain boundaries are mapped, including the iris and the posterior
surface of the lens. The posterior surface of the lens should be determined in order to avoid slit of
the posterior pill. Preprogrammed corneal incisions for temporal injury, paracentesis, and any
optional limbal-relaxing lacerations (LRIs) can be changed at this point to cosmetic surgeon
choice. The pattern is then centered and the laser is turned on.
Utilizing the OptiMedica and LenSx systems, laser-assisted capsulotomy is carried out, followed
by lens fragmentation. This series is justified due to the fact that lens fragmentation causes
release of gas bubbles, which can distort the anatomy and influence capsulotomy planning. If a
corneal laceration is produced, it is the last step before the client is relocated to the operating
room. The stability of the anterior chamber is not interrupted before the client is sterile, as this
preliminary incision does not permeate the posterior corneal surface area. As soon as in the
sterile field, any partial-thickness corneal incisions are then finished with a microsurgical
blade.Clients then undergo elimination of the anterior capsulotomy, followed by conventional
phacoemulsification.
While there have actually been relatively couple of studies showing the energy of FSL in all steps
of cataract surgery, there have actually been numerous publications detailing FSL make use of in
the different steps of cataract surgery We will certainly first evaluate the researches on laserassisted cut, capsulorhexis, and lens fragmentation separately, followed by researches revealing
clinical results.
Regarding capsulorhexis, we hope to comprehend if the enhanced centration outcomes seen with
laser-derived capsulotomy will certainly reveal long-term superiority for visual outcomes and rates
of posterior capsular opacification. This is a sixty-four-thousand-dollar question due to the fact
that positioning of the IOL is the biggest factor to visual mistake after cataract surgery.Las Vegas
