No matter what kind of cataract surgery, intraocular lens implantation is required.

With the increasing demand of the society, Mingshi optometry has actively responded to the policy and implemented the centralized purchase price for all kinds of crystals commonly used in cataract surgery. It can provide single focus intraocular lens, single focus depth of field extension lens, bifocal intraocular lens, trifocal intraocular lens, continuous range intraocular lens, etc. It has covered the mainstream advanced intraocular lens types in the market and can meet the different needs of seeing far, medium and short distance.

1、 Monofocal crystal

It has only one focus. Usually, the doctor will help you set it to "look far", so that you can watch TV, watch the scenery outside the window, drive and look at the road signs in the distance very clearly.

However, the computer screen at medium distance (about 60-80cm) and the books and mobile phones at close distance (about 30-40cm) will be blurred. You need to wear reading glasses or myopia glasses to assist.

2、 Bifocal crystal

It has two focal points, one looking far and one looking close, but there is a "visual fault" between the two at a medium distance (about 50-100 cm). For example, watching computer, cutting vegetables, watching car dashboard and other activities, eyesight will be discounted.

3、 Single focus depth of field extension crystal

The focus of long and medium distance is "elongated" into a continuous and clear line segment. It will be clear and natural to look at the vision, drive at night, and look at the dashboard. You still need to wear reading glasses or myopia glasses to help you see close.

4、 Trifocal crystal

Three clear focal points are set in the long-distance, medium distance and short-distance focal segments, covering the main distance of eyes in life. It is necessary to adapt and find clear distance points after surgery. It is suitable for middle-aged and elderly people who do not want to be bound by glasses.

5、 Continuous range crystal

This is one of the relatively high-end crystals at present, which can be seen as the integration and upgrading of "three focus" and "depth of field extension".

The continuous range crystal can provide smooth and continuous vision in the far, middle and near. It almost eliminates the "jumping feeling" between the focal points, so that you can get a natural and comfortable visual experience whether you are looking at the distant scenery, the dashboard in the middle distance, or the mobile phone screen in the near distance.

6、 Moving trifocal omnipolar

This is one of the relatively high-end crystals at present, which can be seen as the integration and upgrading of "three focus" and smooth phase technology.

It provides clear and continuous motion vision in the distance, middle and near, and excellent medium distance vision, so that patients can truly enjoy a worry free and high-quality life. Whether it is outdoor sports, indoor life, reading calligraphy and painting, etc., it can achieve a continuous breakpoint free vision.
