Question 1

please what malaria drugs are classified as corrective and preventive drugs. please give example?

Accepted Answer

Complicated: Many antimalarials are used both for prophylaxis as well as therapeutics.  Suggest you either get an infectious diseases textbook or go on the cdc website and read about these.  Good luck.

Question 2

what is the highest and the lowest diopter on a corrective lens?

Accepted Answer

+6 to -20: There theoretically is no limit but practical limits are about +6 to -20.  Beyond these ranges, contact lenses, implantable lenses or elective cataract extractions are realistic alternatives (refractive lens exchange).

Question 3

is there a corrective procedure for duane's syndrome?

Accepted Answer

Duane's syndrome: "The goal of treatment is to restore satisfactory eye alignment in the straight-ahead position, eliminate an abnormal head posture and to prevent amblyopia. In most cases, eye muscle surgery is required." See: http://www.aapos.org/terms/conditions/46

Question 4

are glasses and corrective lenses the same thing?

Accepted Answer

Generally: Corrective lenses adjust the focus - they can be glasses or contact lenses.

Question 5

how often does the corrective surgery for asd fail?

Accepted Answer

Very rarely: ASD surgery is usually very successful. There are some types of ASD that are more challenging, and there is a higher risk of having a small residual defect. While not a complete closure, small residual defects are not considered failures.

Question 6

should i get contacts or corrective surgery for astigmatism?

Accepted Answer

Astigmatism: Astigmatism is when the curvature of the cornea is steeper in one axis than another. This causes blur. Contact lenses that correct astigmatism are a good way to correct your vision and if you like how you see lasik is a very safe and reliable way to correct it permanently if you don't want to wear contacts every day.

Question 7

can i determine my vision from my corrective lens prescription?

Accepted Answer

Not really: The numbers in a prescription only define far or nearsightedness and astigmatism.  Rough estimates can be extrapolated from the prescription but can be affected by retinal, corneal or lens disease.  The best way to see what the "best corrected" vision with glasses is to use an eye chart.

Question 8

how are people with glasses (corrective lenses) able to watch 3d movies?

Accepted Answer

Wearing 3D glasses: The 3d glasses can be slipped over the prescription glasses generally without difficulty. Some are very cheaply made from cardboard with thin plastic lenses, but flexible enough to be worn over glasses.

Question 9

how can one gain back his normal eyesight without using corrective spectacles / lenses?

Accepted Answer

Laser or IOL: Laser vision correction (lasik or prk) or refractive lens surgery with placement of an intraocular lens (iol) are other ways to correct your vision. Discuss the various options with your ophthalmologist (eye md) to see what's best for your particular situation.

Question 10

astigmatism might require corrective lenses or glasses. at what level of astigmatism would i need help?

Accepted Answer

When blurred: Astigmatism is very common -- almost everyone has a little bit.  It simply means that the cornea is not perfectly round, but rather has one steeper and one flatter curvature (like the side of a football rather than a basketball).  People with more than 0.75diopters of astigmatism usually notice that images are blurred without glasses or contacts.
