Complications of contact lenses and keratitis Dr. Nir Erdinast
Contact lens complications explanation may irreversibly damage eyesight. Bacterial keratitis (Microbial keratitis) is a common and significant complication among contact lens wearers. Studies have suggested contact lenses companies to invest in solving the anti-pathogenic (against bacteria, viruses and fungi) or cartridge (storage facility Lens) pathogen free transit investment oxygen than contact lenses. In the field of contact lens complications and corneal inflammation Dozens of articles, here are the most important articles published in the field of contact lens complications and corneal inflammation:
Survey research from 2015
Research survey published in 2015 found that the majority of contact lens wearers do not follow the general maintenance (cleaning, disinfection and use) and assembly of lenses. In the survey from 2015 found that about a third adult contact lens wearers (contact lens wearers over 18) having an event of Red Eye (eye redness), pain wearing contact lenses. The study noted that the figures should be higher because research survey covered adult subjects (contact lens wearers over the age of 18) are responsible for a population of contact lens wearers and young people under the age of 18.
Research on complications of contact lenses 2014
In a study published in 2014 and belongs Lkoliar and his colleagues found that the most significant complication called corneal infection (keratitis) and may result in Leoben vision makes about one million visits to professional-ophthalmologist. As well as the rest of contact lenses cause complications Gaza scope of the visits. The study noted that the financial cost of the visits result of complications of contact lenses is huge. The total cost of the visits amounted to complications of contact lenses valued in the amount of $ 200 million.
Risk factors for complications of bacterial keratitis (Microbial keratitis) contact lenses – English study
Dart researcher and his colleagues published a study of UK contact lens complications and article was published in the journal Ophthalmology in 2008. The study determined that the greatest relative risk of developing microbial keratitis (Microbial keratitis) due to contact lens wear. It should be noted that the main reason (Reason No. 1) bacterial corneal infection (keratitis Microbial) among young people is due to contact lens wear. Bacterial keratitis (Microbial keratitis) can cause loss of vision especially in cases where large lighting and is located opposite the center of the pupil (inflammation healing process will result in the formation of scar tissue that does not allow transparency. Then there need cornea transplants return of transparency).
The study found important findings regarding contact lens complications of bacterial corneal infection (keratitis Microbial) in particular:
- The study found that the risk of bacterial keratitis (Microbial keratitis) exceeds 1.56 According to wearing contact lenses overnight stays and decreases according .16 wearing contact lenses difficult.
- According to the study there was no difference between the risk for microbial keratitis (Microbial keratitis) between silicone hydrogel contact lenses and other raw material of soft contact lenses.
- Prolonged assembly (sleeping with lenses) Contact Lenses risk of complications of bacterial keratitis (Microbial keratitis) exceeds 5.4 times
- The risk of vision loss greater wearing contact lenses overnight stays allowing another type of replacement soft contact lenses
- Various companies of contact lenses (different brands of contact lenses) related to a variety of risk factors for bacterial keratitis (Microbial keratitis)
- Bacterial keratitis (Microbial keratitis) with a reduced risk of developing (according to 0.45) if the contact lens wearers are over the age of 50.
- Risk factors for bacterial keratitis (Microbial keratitis) are storage stack of lenses with low hygiene, sleep and sleep often fixed with contact lenses and sex. When the relative risk of bacterial keratitis 5.28 times as much as a regular sleeping with lenses, sometimes according to sleep 1.78 with 1.48 times lenses contact lenses if components are males.
Risk factors for bacterial keratitis (Microbial keratitis) contact lenses – Australian Research
Stfaton Sydney in Australia and colleagues published a study of contact lens complications. This article was also published in the prestigious journal in the field of ophthalmology called Ophthalmology. The article analyzed and examined 285 cases of bacterial keratitis (Microbial keratitis) and 1798 patients in the control group, the study published in October 2008.
The study found significant data regarding contact lens complications and bacterial keratitis (Microbial keratitis) which examined the prevalence of 10,000 contact lens wearers found that:
- 1.2 cases out of 10,000 contact lens wearers suffering severe bacterial keratitis (Microbial keratitis)
- 1.9 Components 10,000 cases of soft contact lenses (daily lineup – Remove the lenses every day) suffered from corneal bacterial (Microbial keratitis)
- 1.9 10,000 cases of soft contact lens wearers (extended composition – sleeping with lenses) suffered from corneal bacterial (Microbial keratitis)
- 2.0 cases out of 10,000 components daily disposable contact lenses (projection in the trash at the end of the assembly) suffered from corneal bacterial (Microbial keratitis)
- 4.2 cases out of 10,000 components daily disposable contact lenses (a long lineup – sleep with contact lenses) suffered from corneal bacterial (Microbial keratitis)
- 0.6 out of 10,000 have lost their sight
- Orders of contact lenses online sites (sites that sell contact lenses online) increased 4.76-fold risk of bacterial keratitis (Microbial keratitis).
- Other risk factors for bacterial keratitis (Microbial keratitis) are storage stack of lenses with low hygiene, smoking, sleeping sometimes with lenses, contact lenses. When the relative risk of bacterial keratitis cartridge costs 3.7 times with poor hygiene, according to 3.96 times sleeping with contact lenses, according to 2.96 from smoking, farsightedness 1.77 times
