Are Cataract Eye Drops a Permanent Treatment?

Currently, the only possible solution for treating cataracts is to remove the opaque lens and surgically transplant another artificial lens. Continuous efforts are being made around the world to develop eye drops that can treat cataracts. But this seems to be a distant reality.

What is a cataract?

The phenomenon of cloudiness or increased opacity of the natural lens of the eye is known as Cataract.. Natural lenses that help focus the light rays that enter the eye on the retina are made up of proteins. When an individual is young, the lens is transparent and transparent. However, with age, proteins begin to aggregate and become less transparent. This is why older people have cataracts. Their eyesight is more cloudy, blurry and hazy compared to the eyesight of young people.

Apparently, scientists are working tirelessly to develop eye drops that can cure cataracts permanently without having to go under a knife.

Eye drops for cataract

In one study, two children who developed cataracts as a hereditary disorder were studied. Both children experienced a gene mutation that prevented their body from producing lanosterol. Lanosterol is a compound produced inside the eye. Surprisingly, none of the parents developed cataracts and did not experience mutations. Researchers have concluded that lanosterol is an important chemical that prevents the natural lens from becoming cloudy due to excess protein accumulation.

Continuing their hypothesis, researchers repeated experiments on human lens cells to see if lanosterol functions in the same way. Interestingly, the result was the same-improved transparency. The experiment was conducted on rabbits and dogs suffering from cataracts. They responded in a similar way.

According to another survey conducted in 2015, the findings were similar to the above experiments. In this research study, scientists studied the effects of compounds (sterols) on amyloid in the eye. Sterols dissolved amyloid (protein deposits) in laboratory dishes. They also concluded that sterols not only lyse proteins, but also prevent the formation of new protein clumps.

In conclusion, both findings of the experiment show the concept that eye drops containing lanosterol can be prepared in the future to treat cataracts.

Add eye drops after cataract surgery

When cataract surgery is complete, doctors prescribe eye drops to reduce the risk of infection and speed up the healing process. In general, the following eye drops are prescribed-

  • Dexamethasone- These drops are steroid-based. It is used to reduce inflammation and pain, and the usual dose is 1 drop, 4 times daily, for 4 weeks. However, check with your doctor for the final dose.
  • Antibiotics- Antibiotics such as chloramphenicol are prescribed to prevent harmful bacteria from colonizing the area around the eyes and causing infection. Antibiotic doses are also 4 times daily for 4 weeks, unless otherwise recommended.
  • Soothing eye drops- The above two types of eye drops prevent pain and inflammation. Soothing eye drops can help deal with itching, clogging of particles, and feeling dry.

How to add eye drops after cataract surgery?

The wounds during cataract surgery are still healed and susceptible to infection. Therefore, it is important to make sure to put eye drops in a timely manner. Often people are unaware of the correct way to put eye drops that can harm the treated eye. A step-by-step guide on how to add eye drops after cataract surgery-

  • Make sure you wash your hands properly before placing the drops. If anyone else is taking eye drops, make sure they also wash their hands. This should be done every time you add eye drops.
  • Sit comfortably and tilt your head back so you can see the ceiling.
  • Gently pull down the lower eyelid with one hand. If another person is taking eye drops, gently pull the upper eyelid with your other hand. Do not do this in case it causes discomfort.
  • Then shake the bottle before using. Keep your hand on the bridge of the nose and follow your doctor’s instructions for support and squeeze the number of drops.
  • Close your eyes and drop any excess drops. Wipe them off with a clean, soft cloth.
  • If you think you are missing drops, repeat the procedure again.

Sometimes, eye drop bottles do not come with an “eye drop dispenser”. In this situation, you should buy from your local pharmacist.
