Embodiment 1

[0024] The present embodiment provides a kind of polishing method of intraocular lens, comprises the following steps:

[0025] S1: Add 700g of glass beads for polishing with a diameter of 1.0-1.3mm, 300g of glass beads for polishing with a diameter of 0.3-0.5mm, 1g of polishing powder, 140mL of purified water, and a sodium hydroxide solution with a concentration of 0.1mol / L in the polishing bottle. 135mL;

[0026] S2: Put the polishing bottle 10 with the content prepared in step S1 on the polishing machine and mix evenly, and the polishing bottle 10 rotates at 80RPM during mixing; figure 1 As shown, the polishing machine includes a frame 20, on which at least one guide layer is set, and the guide layer includes at least two parallel guide rollers 21, and the polishing bottle 10 is a glass bottle with a cylindrical body, so The polishing bottle 10 is laid flat on two adjacent guide rollers 21, the distance between the two adjacent guide rollers 21 is smaller than the outer dia...

Embodiment 2

[0031] The difference between this embodiment and embodiment 1 is that

[0032] In step S1: 700 g of glass beads with a diameter of 1.0-1.3 mm, 300 g of glass beads with a diameter of 0.3-0.5 mm, and 2.5 g of polishing powder are sequentially added to the polishing bottle 10;

[0033] In step S4: the rotational speed of the polishing bottle 10 is 100 RPM, and the polishing time is 72 hours.

Embodiment 3

[0035] The difference between this embodiment and embodiment 1 is that

[0036] In step S1: 700 g of glass beads with a diameter of 1.0-1.3 mm, 300 g of glass beads with a diameter of 0.3-0.5 mm, and 2.5 g of polishing powder are sequentially added to the polishing bottle 10;

[0037] In step S4: the rotational speed of the polishing bottle 10 is 80 RPM, and the polishing time is 72 hours.

Abstract

The invention provides a polishing method of an intraocular lens. The method comprises the steps of S1, sequentially feeding glass beads used for polishing, polishing powder, purified water and sodium hydroxide solution into a polishing bottle; S2, putting the polishing bottle containing the solution prepared in the step 1 on a polishing machine for mixing; S3, putting the semi-finished product of the lens into the polishing bottle in the step 2; S4, putting the polishing bottle of the step 3 on the polishing machine, and carrying out rotary polishing; S5, separating the lens polished in the step 4 from the glass beads. After the polishing method of the intraocular lens is used, the polishing condition is reasonably optimized, so that the technical problems that polishing powder adhesion, salient points, excessively polishing and the like caused by the wrong polishing conditions can be effectively solved.

Description

technical field [0001] The invention relates to a polishing method in the process of artificial lens processing. Background technique [0002] Intraocular lens (IOL) is a precision optical component implanted in the human eye during cataract surgery, and is mostly used to replace the removed self-cloudy lens after cataract surgery. The material composition can be silica gel, polymethyl methacrylate, hydrogel, etc. In the process of intraocular lens processing, its optical properties are mainly obtained by polishing its optical surface. However, in the existing polishing methods, there are often phenomena such as polishing powder adhesion, knife marks, and over-polishing due to poor polishing conditions, which seriously affect the intraocular lens. Optical performance and production efficiency. Contents of the invention [0003] The present invention aims to provide a polishing method for an intraocular lens, which solves technical problems such as polishing powder adhesi...
