Steps in Femtosecond Laser Cataract Surgery

Although the steps for each laser platform differ, they all require 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 dispersing pressure uniformly on the cornea. The docking system minimally misshapes anatomy while enhancing intraocular pressure (IOP), although apparently less IOP increase than seen in FSL refractive surgery. According to Friedman et al., the OptiMedica platform has a liquid optics interface which enhances IOP by 15 mmHg and prevents corneal folds.Laser Cataract SurgeryOther platforms have actually not defined a degree of IOP boost. Once docking is full, anterior segment imaging is then carried out. LenSx and OptiMedica utilize Fourier-domain optical coherence tomography (FD-OCT), while LensAR uses Scheimpflug imaging innovation. This step is required to find anatomical landmarks for laser pattern mapping. It is also important that certain limits are mapped, consisting of the iris and the posterior surface area of the lens. The posterior surface area of the lens have to be identified in order to avoid leak of the posterior capsule. Preprogrammed corneal incisions for temporal wound, paracentesis, and any optional limbal-relaxing incisions (LRIs) can be changed at this indicate specialist choice. The pattern is then centered and the laser is triggered.Utilizing the OptiMedica and LenSx systems, laser-assisted capsulotomy is carried out, followed by lens fragmentation. This series is justified since lens fragmentation triggers release of gas bubbles, which can distort the anatomy and influence capsulotomy planning. If a corneal incision is developed, it is the last step before the client is relocated to the operating room. The integrity of the anterior chamber is not interrupted before the patient is sterilized, as this initial cut does not penetrate the posterior corneal surface. Once in the sterilized field, any partial-thickness corneal incisions are then finished with a microsurgical blade.Patients then go through removal of the anterior capsulotomy, followed by standard phacoemulsification.While there have been relatively few researches showing the energy of FSL in all steps of cataract surgery, there have actually been multiple publications detailing FSL utilize in the different steps of cataract surgery We will certainly first evaluate the researches on laser-assisted cut, capsulorhexis, and lens fragmentation individually, followed by studies revealing medical outcomes.Regarding capsulorhexis, we hope to understand if the improved centration results seen with laser-derived capsulotomy will reveal long-term supremacy for visual outcomes and rates of posterior capsular opacification. This is a sixty-four-thousand-dollar question since positioning of the IOL is the greatest factor to visual error after cataract surgery.Lasik eye surgeryCenter For Sight Las Vegas5871 W Craig Rd, Las Vegas, NV 89130, United States(702) 724-2020http://www.centerforsightlv.com/
