Nd: yag laser capsulotomy and complications

ABSTRACT

To evaluate the complications of Nd Yag laser when applied on postoperative posterior capsule opacification [PCO], following extra capsular cataract extraction [ECCE] with intraocular lens [IOL]. Analytical and descriptive study. Eye OPD of DHQ Hospital, PMC and Clinic of Professor Zia ud Din Ahmad, Faisalabad. From Jan 2006 to Jan 2007. There were 120 patients; age ranged from 15 years to 80 years with post operated extra capsular cataract extraction with posterior capsular opacification. A Proforma was made which included detailed history of diabetes, hypertension, time period of cataract extraction, other relevant surgical or medical history, and examination e.g. Visual acuity, slit lamp examination, intraocular pressure measurement [applanation tonometry] dilated posterior capsule examination and slit lamp biomicroscopy etc. The patients were kept under observation for 5 hour and called for follow up after one week. Out of 120 patient s 70 eyes showed visual improvement from 6/18 to 6/6 [58.34%], while 30 Shown visual acuity improvement from count figures to 6/24 [25%], mild anterior uveitis occurred in 8 cases [6.67%], corneal damage in 2 cases [1.6%] while transient raised Intraocular Pressure [IOP] in 7 cases [5.83%]. The damage to IOL observed in 3 [2.5%], the corneal damage was seen in 2 cases [1.67%]. The Nd; Yag Laser is very effective, cheap and easy mode of treatment for PCO with minimal post laser complications
