A Study of Refractive Errors in Pseudophakia
Journal Title: Journal of Medical Science And clinical Research - Year 2018, Vol 6, Issue 10
Abstract
Background: Cataract is the most prevalent, treatable cause of visual impairment and blindness in the world. Cataract surgery with an intraocular lens (IOL) implant is one of the most common and thought to be the most effective surgical procedure in any field of medicine. Very few studies had documented the refractive error in a pseudophaki patients. Objectives: To find out the pattern of refractive error among the pseudophakic patients. Material and Methods: Its descriptive hospital based study done among 100 psudophakic patients attending the department of ophthalmology 6 weeks after the cataract surgery between Oct 2017 and Oct 2018. Results: 80% of the study participants were between 60 to 80 years. 51% of the study participants were males. 81% had undergone Manual SICS and 24% had uncorrected visual acuity of 6/18, 22% had 6/12 and 21% had 6/9.Residual spherical refractive error in pseudophakics ranges from -3 to 1 DSP. Most of the study particpants’ spherical refractive error falls between -0.5 to + 0.5 (84%). Post-Operative near Vision Accommodation needs to be corrected with +2.5 for monofocal IOLS. The residual post-operative astigamatism was more frequently an against-the-rule Astigmatism, ie, -0.5 to -1.00 at 90 DCP. Conclusion: The psududophakic patients using monofocal IOLs and undergoing manual small incision cataract surgery are having less refractive correction and Against the rule astigmatism is produced due to corneo scleral scarring. The near vision correction is to be done for all the patients who are using monofocal IOLs.
