Lasers help bring cataract surgery in focus

Exclusive to the Acorn group of newspapers

There are a number of advantages to using the laser in cataract surgery. Mainly, the surgeon can plan the exact size of the eye capsule opening that is needed for the replacement lens. With lasers, the doctor can also determine the exact pattern in which the old lens will be broken up.

Tests prior to the procedure include obtaining a colored image of the surface of the eye and measuring the length of the eye.

A detailed clinical slit exam is required to assess the thickness, color and hardness of the problem lens. Any weakness in the support of the lens or abnormalities on the lens capsule must be spotted.

This information leads to a plan of action which is entered into the laser software. Modifications can be programmed and, in difficult cases, a second opinion can be obtained.

Laser cataract surgeryis safe as it does not stress the lens capsule or its support. The same holds true in traumatic cataract cases where trauma weakens the support.

Use of the laser is beneficial in making openings in eyes with thick capsules such as those of children.

In people with white or red cataracts, the capsule needs to be stained manually to be visualized, and still it may be difficult to get a good view of the area. The laser overcomes this challenge as it employs imaging in real time and vertical cutting to avoid any traction on the zonular support system.

The laser precision is equally useful in wound creation. The precise openings allow the entry and exit of instruments and insertion of the pi without undue stress and consequently inadvertent enlarging of the wound. This prevents wound leakage at the end of the case and faster healing.

The opening in the lens bag or capsulorhexis is made first. This is followed by the patterned breakup of the lens. It can be cut into 2, 4 or 6 pieces. The center core may be delineated too. The depth of these lenticular cuts can again be controlled.

The depth of the cuts can be controlled in real time. The energy is delivered from the bottom towards the top. This allows gas generated by conversion of the lens material into plasma to escape as well allow the subsequent beam to work without interference from the gas bubbles. The option till now was to use sound energy. This can cause inflammation and affect the functioning of the cornea. In dense cataracts the bottom is difficult to perceive so the capsule can be accidentally ruptured. Again, the real time display and the ability to be precise and avoid the bottom of the bag is a boon when using the laser for cataract or Prelex procedure. Lets talk about breaking these hard lenses. It’s a real pain for the surgeon and patient alike to work on these cataracts with sound wave technology. It takes times and a lot of energy to accomplish this with traditional technology. This is where progress in laser technology will help even more in the future.
