With the advent of "Robolaser" or Femtolaser cataract surgery, many patients are confused about the differences. Here are the facts and myths to help you make an informed decision.
1. Is surgery performed by a computer/robot?
Fact: Only the corneal incisions, capsulorhexis, and breaking of the nucleus into fragments (initial few steps) are done by the femtosecond laser machine. The rest of the surgery is performed as routine conventional Phacoemulsification surgery by the surgeon on the same machine.
2. Is it a painless surgery?
Both are similar: Both conventional Phacoemulsification and femtolaser cataract surgery are performed under Topical or Local anaesthesia. Both surgeries have no difference in relation to pain; it depends upon the patient's threshold to perceive pain in both scenarios.
3. Is it bloodless?
Yes: Cataract surgery is usually a bloodless surgery, whether performed by conventional phacoemulsification or with femtolaser.
4. Is it a fast surgery?
Conventional is often faster: Conventional Phacoemulsification usually takes less time. Femtolaser cataract surgery is performed on two different machines; first, the laser does the initial part, and then the patient is shifted to the regular operation theatre, increasing the total procedure time.
5. Is Phacoemulsification not required?
Incorrect: Only the initial cuts in the cornea, capsulorhexis, and nucleus fragmentation are made with the femtolaser. The remaining procedure for phacoemulsification is performed in the OT with the same machine.
6. Is it Sutureless?
Both are sutureless: Usually, both are sutureless surgeries. However, sometimes a suture may be required in both surgeries to seal the incisions effectively.
7. Is the lens inserted by the robot?
No: The doctor inserts the lens in the eye in both surgeries after finishing phacoemulsification. Any type of foldable lens can be inserted after either procedure.
8. Is it complication-free?
Not necessarily: Incomplete cuts made in the cornea and capsule by the laser can lead to complications, and the same incisions may need the blade used in conventional surgery to open them.
9. Are precautions required?
Yes: Standard precautions, care, and medications are required after both conventional Phacoemulsification and femtolaser cataract surgery.
10. Faster Healing?
Advantage Femtolaser: As the incisions are created with laser, patients usually have a faster recovery compared to conventional phacoemulsification.
Conclusion
Conventional Cataract surgery is very effective and safe. People who do not want to invest too much money can still opt for conventional Phacoemulsification. However, Femtolaser cataract surgery is a new technology and can be opted for in selected cases where cost is not an issue.
