The concept of “disposable” has consumers become familiar with the wide range of disposable products such as cameras and razors. The recent introduction of disposable contact lenses has aroused great interest and has disposable culture facilitated the rapid penetration of these on the market.
In most countries it has been recommended use of disposable contact lenses: this is that the patient had to insert the lenses and leave them in the eye to thirteen consecutive days. The lens then had to be removed on the last night and a fresh pair of lenses had to be inserted the following day and thus cycle continued. Using disposable contact lenses even at night had limited success before. It was anticipated that the replacement lenses regular reduce the incidence of complications returning the lenses to use at night safer.
Although there are many benefits of disposable contact lenses there is recent evidence of potential complications with this variety use of contact lenses. The International Committee on Contact Lenses (ICCL) considers it necessary to evaluate the recent clinical information and scientific relevance of disposable contact lenses and issue this document with recommendations and advice of the experts in the contact lens. This initiative is made for purpose of promoting safe and effective using disposable contact lenses.
Production of disposable contact lenses
The disposable contact lenses currently on the market are made hydrophilic polymers that are nontoxic, designed to have minimal physiological impact on the tissues of the eye. They are made of materials that appear in two categories of the Food and Drug Administration of United States (FDA). Materials Type I (low water content and nonionic properties in the area) and Type IV materials (high water content and ionic properties of the surface). These properties are important when interpreting the clinical activity of the disposable contact lens.
Disposable contact lenses are found in small packages that are delivered directly to the patient representing a shift in the traditional practice for the specialist all lenses examined before being placed in the eye. Thus the responsibility for providing significant defect-free glasses is transferred to the producer. New techniques have been developed and existing ones modified, to allow a large number of lenses are manufactured with good reproducibility. While some small defects have been reported, clinical significance is not understood completely, but these studies are needed.
