[What is cataract]

Cataract is an eye disease that causes the "lens" in the eye to become cloudy, causing it to look hazy, to feel glare, and to impair vision.

If you do not operate early, complications may occur and lead to blindness in rare cases, and the difficulty of surgery may increase. In other cases, it is not too late and you should perform surgery if you feel inconvenience . It is advisable to see an ophthalmologist without making any judgment. ​

​

​

[Cause]

These include the effects of UV and radiation , aging, trauma, drugs, and other illnesses such as diabetes and atopic dermatitis .

Most of them are due to aging, and basically most people get cataracts when they get older.

​ [Countermeasures at eyeglass stores]

At our shop, we recommend that you see an ophthalmologist because you can guess that you may have cataracts if your eyesight is not so good even if you adjust the power of your glasses .

Cataracts can only be completely cured by surgery so far , and doctors will comprehensively judge various things and consider treatment methods.

​ Also , since the power changes after cataract surgery , it is necessary to make glasses with a new power.

[Postoperative eye]

The power of the intraocular lens is determined by the doctor's judgment according to each life.

A normal intraocular lens does not have a function to adjust the focus, and it cannot be seen clearly except at a certain distance.

In the case of a bifocal intraocular lens, you can temporarily see it from far to near with the naked eye, but as the power changes over time , you will need to use glasses or contact lenses.

​

◆ Eye condition of normal intraocular lens

Roughly classified

​

・ You can see well in the distance ⇒ Characters are difficult to read ( no power or weak hyperopia )

・ Characters can be seen clearly ⇒ I can't see well in the distance ( myopia )

・ You can see the middle distance well ⇒ You can't see far and near a little ( weak myopia )

 

I think that it will be in such a state.

Also, the state changes over time. ​​

​

◆ Postoperative astigmatism

Astigmatism may occur even after inserting the intraocular lens.

Astigmatism is present in most people, regardless of their strength, and even if they think they are clearly visible, they may look blurry or tired easily if they watch letters or TV for a long time.

​

◆ Postoperative left-right balance

Even after inserting the intraocular lens, the left and right dioptric powers may not be the same.

If your eyes don't look well-balanced, you 're more likely to get tired.

​

◆ Postoperative oblique position and strabismus

Cataract surgery does not eliminate the slanting or strabismus that makes you look like two things or makes your eyes tired easily.

You may need glasses that incorporate prism correction.

​

​

[Glasses after cataract surgery ]

After inserting any intraocular lens, the eyesight improves and the brightness of the field of vision improves compared to before surgery, so many people feel that they can live without glasses.

However, you will need glasses to comfortably see both in the distance and at hand .

Also, pre-surgery glasses are not comfortable because the power changes after surgery.

You will need glasses that match your eye condition and living environment after surgery.

​

[Cataract surgery]

A common cataract surgery is to remove the cloudy crystalline lens and insert an "intraocular lens".

Some intraocular lenses are not covered by insurance and require a high burden, but it seems that some intraocular lenses are bifocal.
