What is the difference between Bausch Lomb 1 8 intraocular lens and Alcon IQ intraocular lens?

Bausch & Lomb intraocular lens, 1. Hydrophilicity.

Acrylic component (HEMA) to make IOL implantation easier compression folding necessary for the fabrication of micro-incision (mm) intraocular lenses.

2. Aspheric zero aberration optical surface, good visual effect, 3. The design of the pouch is 10 degrees angled, closer to the posterior capsule, and the design of the four flaps is evenly stressed, and the end of the absorption zone conforms to the peripheral part of the capsule, so as to absorb the pressure of the capsule contraction and stabilize the center.

From the point of view of Bausch & Lomb is a little more expensive than Alcon.

Both brands are very good.

At present, the most commonly used intraocular lens brands in China include OII, Alcon, Bausch & Lomb, Aofe, etc.

Among them, Alcon procures intraocular lenses for the vision restoration project of the China Disabled Persons' Federation.

Intraocular lenses, (IOLs). It is an artificial lens that is implanted in the eye to replace the role of the natural lens. The first intraocular lens was designed by John Pike, John Holt and Hardold Ridley, and on November 29, 1949, Dr. Ridley implanted the first intraocular lens in a patient at a London hospital.

In World War II, it was observed that some injured pilots had glass shrapnel in their eyes, but did not cause a significant, sustained inflammatory response, so they thought that glass or some polymer organic material could remain stable in the eye, and thus invented the intraocular lens.

The shape of the intraocular lens is usually composed of a circular optical part and a peripheral support loop, the diameter of the optical part is generally about the same, this is because, at night or in dark light, the human pupil will be dilated, the diameter can reach about 6mm, and the oversized intraocular lens has certain difficulties in manufacturing or surgery, so the main manufacturers use the diameter of the optical part. The function of the support loop is to fix the intraocular lens, and there are many forms, and the basic ones can be two C-shaped wire-mounted support loops.

Bausch & Lomb intraocular lenses, 1, hydrophilic acrylic components (HEMA), make it easier for IOL implantation to compress fold the necessary conditions for the manufacture of micro-incision (mm) intraocular lenses. The refractive index is close to the refractive index of the human eye).

2. Aspheric optical surface with zero aberration, consistent diopter from ** to edge, and stable visual effect.

3. The design of the pouch is 10 degrees angled, closer to the back capsule, the design of the four flaps, the force is uniform, and the end of the absorption zone conforms to the peripheral part of the capsule, so as to absorb the pressure of the capsule contraction and stabilize the center.

The eyesight ranking is in the first echelon, and the American Univision is in the second echelon.
