What the Surgeon Needs During the Laser Cataract Course

1-    Overview of the Laser Cataract Course

One of the most common surgeries in the world today, the removal of the hazy natural lens
from the eye, known as cataract surgery, is an ever-evolving and vibrant
subspecialty in the field of ophthalmology.

The traditional cataract surgery When a manual incision is made,
the wounds rely on the patient’s natural healing process,
which is variable and often leads to poor wound construction and an unstable ocular surface.
A relatively new technique in cataract surgery incorporates the use of a femtosecond laser.

This type of laser uses near-infrared light that can make very fine and precise cuts in a variety
of tissues within the eye, including the cornea, lens, and corneal incision.
The laser uses very short and quick pulses and can be positioned accurately,
reducing collateral tissue damage.
This technology allows surgeons to plan and perform incisions, astigmatism correction,
and capsulotomy with enhanced precision.

Through the laser cataract course, will train on this technology.

2-    Presentation Evolution of Laser Technology in Cataract Surgery

 lasers are not used to remove the cataract itself from the eye; the laser and its associated
technology are used to perform key parts of the preparation for the cataract’s removal,
such as creating the incisions in the cornea and the circular hole in the capsular
bag through which the clouded lens will be removed

The use of a laser to perform these steps offers the potential for greater accuracy
than the traditional methods of creating these incisions – the laser can be directed
to create incisions to fractions of a millimeter, and it has also been found to be able to create reproducible,
precisely sized and accurately positioned incisions with a much higher degree
of certainty compared to those performed manually.

The key concept behind laser-assisted cataract surgery, as well as the other types
of modern cataract surgery, is to use lasers and technology to minimize the manual parts of the procedure.

The expected benefits of laser cataract surgery include greater precision in performing
the key steps listed above.
Just as with computer-guided laser eye surgery and the most modern forms of cataract surgery,
this tailored approach has the potential for improved visual outcomes and reduced risk
of complications compared to the traditional ‘one size fits all’ manual cataract removal procedure.

The nineties saw vast improvements in the technology and technique of cataract surgery
on a couple of fronts. On the one hand, phacoemulsification, or ‘phaco’,
revolutionized the way cataract surgery was performed.
Phacoemulsification uses ultrasonic energy to emulsify or break up the cataract,
and then vacuum the pieces out of the eye through a small incision.
The surgeon inserts a tiny probe into the eye that emits the ultrasound waves
which soften and then break up the clouded lens.
This process allows for a much smaller incision, usually around 3mm or less,
and is considered a ‘minimally invasive’ procedure.
The small incision size often allows the eye to heal more rapidly, less astigmatism is induced,
and it also often means that a suture isn’t required to seal the incision.

This type of surgery quickly became the most common and successful method for cataract
extraction around the world and is what most people would consider to be ‘modern’ cataract surgery.
