Some of the newer lenses are being designed with the idea that we want to maximise
myopic management.
Eighty
myopic eyes of guinea pigs were collected as described above, randomly divided into five groups (16 eyes each): group E (0.5% LOX), group F (1% LOX), group G (0.1% LOX + 1% GNP), group H (0.5% LOX + 1% GNP), and group I (1% LOX + 1% GNP), and allowed to react for 4 h.
The aim of this study was to find out the visual outcome of high
myopic patients after clear lens extraction and implantation of foldable IOL.
'Indian media taking a
myopic view is selectively showing Mr.
Jeanette Romualdez warns that, "high levels of myopia increase the risk of eye diseases such as cataracts, glaucoma, retinal detachment and
myopic macular degeneration .
Normal control and
myopic groups were recruited from October 2012 to March 2013.
All the thickness values were found to be thinner in the
myopic eyes than in the hypermetropic and emmetropic eyes for all, excluding the LT sub-quadrant.
They found that every additional year of education was associated with a more
myopic refractive error of -0.18 dioptres per year.
Many studies have reported strong links between education and myopia, but it is not clear whether increasing exposure to education causes myopia,
myopic children are more studious, or socioeconomic position leads to myopia and higher levels of education.
Approximately 30% of
myopic patients have high myopia.1,2
Myopic shifts of this degree can seriously impair vision and cause irreversible degenerative changes in the chorioretinal layer3 Retinal tears, retinal detachment, primary open-angle glaucoma, and visual field losses are common in these patients as myopia progresses with aging and the axial length of the eye continues to increase.1,3,4 Current treatments for high myopia still do not yield satisfactory results and there is no proven method of preventing high myopia.
A study with this same approach, carried out by Savini and coauthors in Italy, found that the difference between the simulated keratometry values (SimK), calculated with Sirius[R] corneal tomograph (CSO-Costruzione Strumenti Oftalmici, Florence, Italy), before and after refractive surgery, underestimated the refractive change after the
myopic correction and overestimated it after the correction of hyperopia.
Group1: high
myopic children (>-6.00 D) and Group 2: healthy age matched controls (-1 to +2 D).
