Doing cataract surgery and presbyopia correction, why not a lot

A healthy old man in his mid-seventies enters the clinic.

"A month ago, my eyes seemed pale and troubled, so I went to see an ophthalmologist near the house and found that it was a problem. cataract."

Yes, we tested cataracts.
"So, I want to do surgery, but on the Internet, cataract surgery and presbyopia surgery are also accompanied by what?"

If you can explain easily,

The structure of our eyes is very similar to the camera. The iris is the iris of the camera and the lens of the camera is the lens behind the iris.

The lens is about the size of a baby's fingernail, it has the shape of a smooth head, it is thickened, it becomes thin and it focuses. This lens should be transparent as crystal, but it becomes cloudy or hardened by cataracts.

It is common for cataracts to be unclear even with glbades. In the case of nucleated cataracts in which the central part of the lens is hardened, newspapers or smart phones can be seen easily even without a magnifying glbad at the beginning.

I had used to say that I had rejuvenated it before, but the fact was that the nucleated cataract was happening. As the cataract of the nucleus progresses further, it becomes visible further and further away, and eventually the operation becomes necessary.

In the past, cataract surgery was technically problematic in the past, but cataract surgery was necessary if cataracts increased by more than 70% to 80%, but these technical problems are nowadays resolved and the patient's discomfort greatly reduced. .

Assuming that the stage of cataract goes from stage 1 to stage 5, if the cataract is not uncomfortable even at stage 4, stage 5, If you feel, do the operation immediately.

The operation involves removing the opacified lens by ultrasonography and inserting an intraocular lens to replace it behind the iris. Depending on the type of intraocular lens to be inserted, general cataract surgery is distinguished from cataract surgery by correction of presbyopia.

In the case of cataract surgery, one must focus on the distance and use a magnifying glbad near the center because it inserts a focal lens, which is a focal point, but using a lens intraocular to resolve presbyopia. Therefore, like multifocal lenses, it can attenuate the near-disturbance that is the main symptom of presbyopia.

In the future, cataract surgeries may look like cataract surgery for uncorrected presbyopia, but this is not the case. More than 90% of cataract surgeries currently performed are general cataract surgeries.

This means that even general cataract surgeries can satisfy all physicians. The current supplementation of presbyopia correction cataract surgery is not as perfect as expected and it seems more appropriate to say "a certain amount of complementary" in order to express a personal opinion.

In fact, the correction of presbyopia has not been made suddenly recently. I have developed many presbyopia corrective lenses in recent decades, but I have not been able to market them because of blur, blur, night vision and others. problems.

Presbyopia-corrected intraocular lenses (IOL) have improved many of these problems, but I should not overlook the fact that fewer patients can not adjust to intraocular lenses and replace them with intraocular lenses. normal.

Correction of Presbyopia Cataract surgery is the right direction for cataract surgery and the correction of presbyopia, but it is not over yet. There are, of course, many patients who are very satisfied and well suited to cataract surgery by presbyopia correction. Therefore, a precautionary approach that takes into account the patient's age, occupation, bad, and lifestyle should be considered when determining presbyopic cataract surgery.
