Technical process of RPG lens matching in Zhongshan Ophthalmology Department
Ophthalmic RPG glasses matching is a professional and accurate work, which involves the judgment of the patient's glasses degree and the correct lens selection. The following will elaborate on the RPG lens matching technology process of Zhongshan Ophthalmology Department from four aspects.
1、 Patient eye examination
Before RPG lens matching, the doctor needs to carefully check the patient's eye condition. This process usually includes measuring pupil size, corneal curvature, eye axis length, etc. to ensure accurate degree information. By using professional equipment, doctors can accurately measure these parameters and record them in files.
Next, the doctor will also check the intraocular pressure and corneal diopter, which can help the doctor eliminate other factors that may affect vision, and further improve the accuracy of lens matching. All these examinations are based on modern ophthalmic technology, fast and painless.
According to the individual differences and eye examination results of patients, doctors will combine experience and professional knowledge to develop a suitable RPG lens matching scheme for patients.
2、 Determination of glasses matching degree
In the process of RPG glasses matching, doctors need to accurately judge the degree of patients' glasses to ensure the quality of glasses and the correction effect of vision. The doctor selects the appropriate lens degree according to the patient's vision and different examination results.
Generally speaking, doctors will determine the degree according to the patient's needs for glasses and vision. RPG glasses usually include spherical lens degree (myopia or hyperopia), cylindrical lens degree (astigmatism), axial position and other parameters.
In Zhongshan Ophthalmology Department, doctors not only rely on visual inspection and patient description to determine the degree, but also use precision equipment such as automatic refractometer, corneal topography meter, ultrasonic biometer, etc. to improve the accuracy of judgment.
3、 Lens selection and processing
Lens selection and processing is a very important step in the RPG lens matching process. Zhongshan Ophthalmology Department provides a variety of lenses and selects the most suitable RPG lenses according to different degrees and vision needs.
First of all, doctors will select appropriate lens materials, such as CR-39 plastic lens, high refractive index lens, and anti blue lens, according to the patient's degree and use requirements. Different materials have different characteristics, advantages and disadvantages, and doctors will choose them according to the specific conditions of patients.
Then, doctors will design and order corresponding RPG lenses according to the degree and individual differences of patients. Lens processing usually includes cutting, polishing, coating and other steps to ensure the quality and comfort of the lens.
4、 Matching and adjustment
The last stage is matching and adjustment. The doctor will let the patient try on the newly equipped RPG lens to evaluate its comfort and vision correction effect. Doctors will communicate with patients to understand their feelings and feedback, and make necessary parameter adjustments to achieve the best visual correction effect.
Zhongshan Ophthalmology Department is equipped with advanced optometry room and optometry equipment, which can conduct accurate optometry inspection and adjustment. The doctor will communicate with patients, answer their questions, and provide necessary eye care suggestions and maintenance methods.
epilogue
The RPG lens matching technology of Zhongshan Ophthalmology Department is rigorous and accurate. From eye inspection, degree determination, lens selection to fitting and adjustment, every step has been carefully considered and dutifully operated. With professional technology and equipment, Zhongshan ophthalmologists can provide personalized RPG lenses for patients to achieve accurate vision correction and improve the quality of life of patients.
