A new medical invention has been created by scientists at Harvard Medical School.
The new invention is a contact lens that can dispense a regular dose of antibiotics to your eye for more than a month.
A biodegradable polymer film is mixed with a medication (antibiotic) and coated with hydrogel, which is the same material used to make contact lenses.
The film slowly releases the medication into the eye at a rate of 134 micrograms each day for 30 days.
Eye drops are used to dispense most eye medications but they are inefficient.
Only about 1 to 7 percent of eye drop medications are absorbed into the eye because most of it drips out.
Patients find eye drops cumbersome and often forget to take them, which is why scientists believe this new medical invention will dispense eye medication more easily and effectively.
Contact lenses manufactured from silicone hydrogel represent the most important advance in soft contact lens technology in recent years. Wearers would obviouly prefer lenses they can sleep in with total safety, so it was only a matter of time before the industry developed a safe product for continuous wear. After years of ongoing development and testing, such lenses are now readilly available for everone to wear at an affordable price. This article looks at what's so special about silicone hydrogel lenses and why they might be just the right choice for you.
