Description

Suitable for highly myopic cataract surgery diopter adjustable protective goggles

technical field

The invention belongs to the field of medical protective products, relates to ophthalmic postoperative protective goggles, in particular to a protective goggle suitable for high myopia and adjustable diopter after cataract surgery.

Background technique

It is disclosed in the prior art that high myopia cataract refers to cataract patients whose axial length is greater than or equal to 26mm. Such patients usually have myopia exceeding -6.0D or even -30.0D before surgery. After cataract surgery, a certain degree of low myopia (myopia of about -2.0 to -5.0D is reserved according to the preoperative axial length) is usually reserved to preserve the patient's near vision and maintain the previous living habits. In clinical practice, since it takes a certain amount of time for the diopter to stabilize after cataract surgery, it is usually not recommended for patients with high myopia to have optometry in the early postoperative period. It is generally recommended to wait for about one month, and during this period, the uncorrected vision of the patient cannot meet the requirements for distance vision. Some patients are unable to take care of themselves due to reserved high degrees of myopia and poor uncorrected vision, so they urgently need to wear glasses early after surgery. According to market research, the price of optometry in a regular optical shop or hospital is relatively expensive. If the glasses are ordered immediately after surgery, the glasses generally need to be replaced after one month, which causes unnecessary financial burdens on patients. At present, there is no temporarily diopter-adjustable vision-improving device suitable for use after cataract surgery for high myopia on the market. According to clinical investigations and studies, cataract patients with high myopia have exceeded 30% of cataract patients in tertiary hospitals, and there is an increasing trend year by year. Therefore, the market urgently needs such an eye mask with adjustable diopter suitable for cataract surgery for high myopia.

Based on the fact that cataract patients need to wear protective goggles to protect the operating eyes within one month after surgery, which can avoid accidental bruises and reduce the chance of infection to a certain extent, but the current goggles are mostly metal goggles with a small hole design, and their aesthetics are poor. , and does not have the diopter, and cannot temporarily improve the current situation of postoperative visual acuity of patients with high myopia. The inventor of the present application provides a protective goggle suitable for high myopia after cataract surgery with adjustable diopter. In the present invention, the protective function of the goggle Combined with the diopter of spectacle lenses, it can be made into an adjustable diopter eye mask, which can greatly improve the early postoperative vision of cataract patients with high myopia and improve the quality of life.

Contents of the invention

The purpose of the present invention is to provide a diopter-adjustable protective eyewear suitable for cataract patients with high myopia based on the status quo of the prior art and to make up for the market gap of the existing functional protective eyewear after cataract surgery.
