Visual Outcome in Cataract patients undergoing Phacoemulsification with greater than 23 mm of Axial Length (A study report).
Ophthalmol Update Jan ;15(4):404-7.

Background: A cataract is a dense, cloudy area that forms in the lens of the eye. About 2 million people are blind in Pakistan. Phacoemulsification is most popular method for treatment of cataract. This technique requires a small incision and surgery is suture less. This equipment is very expensive. Objective: To investigate the visual outcome for cataract patient undergoing phacoemulsification in eye with greater than 23mm of axial length. Material and Method: It was a cross sectional study. Cluster sampling technique was used to recruit in the sample. Visual acuity was assessed at a distance of 6 meters of both eyes separately. Then pinhole test was conducted to differentiate the cause of decrease vision. In case of cataract vision was not improved. Keratometric reading of the cornea was measured and the difference of k-reading was taken as astigmatism. Auto Refactor (AR) for total refractive power of the eye was used. Biometry was done for measuring axial length of eyeball. This procedure will be conducted before and after surgery to see the visual outcome after surgery. Data was analyzed with SPSS version 17. Results: From selected 1-50 patients of cataract 32 patients (64%) have visual outcome of visual acuity is 6/6-6/9 after phacoemulsification. Maximum visual acuity with pin hole after phacoemulsification is78 %( 39) is 6/6-6/9.Maximum astigmatism after phacoemulsification is 44 %( 22) 1.00-2.00DMaximum axial length after phacoemulsification is 24 %( 12)23.00-24.00mm. Maximum IOL power is 22 %( 11) have 16.01-17.00D. Conclusion: it is concluded that axial length 23-25mm do not cause refractive error of asymmetry in eyes.
