Laser Cataract Surgery
In suitable patients, up to two thirds of cataract procedures are now performed by LenSx at our practice. Patients are choosing LenSx due to its added precision and reliability. Other reasons include the state of the art technology, its application and the comfort and ease of the procedure. The procedure using LenSx is being proven to be as safe as conventional cataract surgery.
A significant Australian trial of participants showed that it is safer than all published trials of cataract surgery under key indices. The eye receives less wear and tear from this procedure as less internal energy is utilised during the procedure than standard procedures.
The surgery experience only differs slightly from standard surgery. The laser treatment is performed in a dedicated laser room. The laser interface docks painlessly onto the anaesthetised eye and the procedure takes only two minutes in total. We then move into the operating theatre where the procedure is completed in the usual way.
Post op results are positive with patients being very happy with the procedure and outcomes.
Laser cataract surgery has allowed eye surgeons to substitute the first three manual steps of the operation. These three steps include the surgical incisions to the cornea, the formation of the
capsulotomy and the gradual fragmentation of the original lens. Traditionally, surgeons would use a hand-held metal or diamond blade to make the incision where the sclera meets the cornea. However, laser technology now provide surgeons with a sophisticated 3-D image of the eye called an OCT (optical coherence tomography). The image ensures the incision will be of a precise location, length and depth. The technology removes the variability of surgeon practice, improves incision accuracy and may reduce the risk of infection.
Once the incision is made, the front portion of the capsule is removed to gain access to the cataract; a process called capsulotomy. Damage to the capsule is to be avoided, as the capsule will hold the artificial lens in place. Once an opening in the capsule is made, the capsule is torn in a circular motion, creating an opening of 5 to 6mm in diameter and well centered for the optimum implementation of the new lens. By using laser technology, this precise and technical process improves overall accuracy of the capsulotomy, leading to better positioning of the intraocular lens (IOL). Correct placement of the IOL considerably contributes in determining final vision results for patients.
The cataract is then removed after the capsulotomy process is complete. The laser method enables the original cataract to be softly broken into small pieces, requiring less energy than traditional surgery. The process of removing the cataract using laser surgery also reduces the possibility of capsule breakage. Besides the calculation of the correct implant power required, a key factor for superior vision is the preservation of the capsule where the original lens was initially located. It is important to reduce overall damage of the capsule so the artificial lens can be implanted correctly for optimal vision.
Your surgeon and staff can help you with finding information about costs and whether cataract surgery is the right treatment for you.
