The femtosecond laser technology introduced all new levels of safety, accuracy and obviousness to the LASIK surgery and rather a growing trend in laser-assisted cataract surgery in Dubai. At some facilities, it’s known as Refractive Laser-Assisted Cataract Surgery whereas laser cataract surgery in general.
An advanced and precise femtosecond laser either replaces or assists manual surgical equipment for the following steps critical to perform cataract surgery in Dubai;
- The Corneal Incision
- The Anterior Capsulotomy
- Lens and Cataract Fragmentation
Using laser technology ensures a higher degree of precision and reproducibility for each of the steps thereby potentially reducing risks and improving visual results of the cataract surgery.
The Corneal Incision
Traditional cataract surgery is most frequently performed and considered safest and effective with conceivable outcomes backed by surgeon’s expertise, volume and industrial practice. The first step is making an incision in the cornea which in traditional method would’ve been done with a manual surgical tool made of stainless steel or diamond blade in the area where cornea meets the sclera. Surgeon would then access interior of the eye for breaking up and removal of the cataract; the clouding of the natural eye lens right behind the pupil.
With laser assisted cataract surgery in Dubai, surgeon creates a precise plan for the corneal incision supported by a 3D graphical imagery of the eye known as Optical Coherence Tomography (OCT). The goal is creating an incision in the precise location with accurate depth and length in all planes with OCT image and a femtosecond laser for exact performance. This is important not just for the accuracy but for increased likelihood that incision would self-heal by the end of the procedure thereby reducing the risk of infection.
The natural eye lens is surrounded by thinnest and a clear capsule. With the surgery, front portion of the capsule is removed which is known as anterior capsulotomy thereby gaining access to the cataract. It’s important for residue of the lens capsule to remain intact in the eye for it holds the artificial lens implant in position.
The traditional cataract surgery is carried forward with a surgeon making an opening in the capsule with a micro needle and tear the capsule in circular fashion using either the same needle or forceps.
In laser cataract surgery, anterior capsulotomy is performed using femtosecond laser. Studies revealed that capsulotomy performed with laser technology have far greater accuracy and reproducibility.
Lens & cataract division
Once capsulotomy is performed, surgeon have access to the cataract for removing it. In traditional cataract surgery, an ultrasonic device which fragments the cataract is then implanted into the incision. During the phacoemulsification, this ultrasonic energy builds up heat in the incision which may have an adverse outcome such as induction of astigmatism.
Laser on the contrary softens the cataract as it breaks and less energy is required for complete removal hence no chance of burning and distortion of the incision.
Laser assisted cataract surgery is regarded safest and most radical development in eye care industry.
