The prevalence rate of nearsightedness was 71.22%, among which there were 1595 males (66.84%) and 1763 females (75.56%) with a male-to-female ratio 1∶ 1.11. The sex diversity of prevalence rate was statistically significant (χ 2=45.029, P< 0.001).
This paper studies the clinical effects of injection puerarin in treating retinal arterg venous blocks and nearsightedness. Result shows that its effects is Very good and in superior to other medicines,may be treated nearsightedness,its treating mechanism Was preliminary in vestigated.
Conclusions:The prevalence rate of nearsightedness is high in teenagers and females have higher ratio of prevalence rate, which demonstrates that the occurrence and progress of nearsightedness is closely related to near-reading .
Although the myopia can be corrected by the laser in situ keratomileusis (LASIK) in a certain degree, it brings about negative effects under scotopic conditions.
Results: Seventy-five percent of the sample had impaired DVA; 39 % of the subjects had refractive error (myopia).
Phototherapeutic keratectomy combined with photoref ractive keratectomy for treatment of myopia with corneal scars
To evaluate the effect of phototherapeutic keratectomy combined with photoref ractive keratectomy in the treatment of myopia with corneal scars, corneal epithelium was removed with laser plus scraping.
Corneal scars were removed with PTK, followed by PRK for myopia.
Comparison of high order aberration after conventional and customized ablation in myopic LASIK in different eyes of the same pat
Purpose: To verify whether there exists any difference in higher order aberrations after undergoing myopic LASIK (laser in situ keratomileusis) with conventional ablation and customized ablation in different eyes of the same patient.
Methods: This was a prospective randomized study of 54 myopic eyes (27 patients) that underwent LASIK using the Nidek EC-5000 excimer laser system (Nidek, Gamagori, Japan).
The results of computer experiments on the diagnostics of degenerative myopic retinoschisis and X-chromosomal retinoschisis are presented in the paper.
Correcting the corneal power measurements after myopic laser In Situ keratomileusis
