Visual outcome and complications after modified Cionni endocapsular tension ring and intraocular lens implantation in eyes with subluxated lenses

To evaluate the visual outcome and complications after modified capsular tension ring [CTR] and intraocular lens implantation [IOL] in eyes with subluxated lenses. This is a prospective case series managed at Al Shifa Trust Eye Hospital, Rawalpindi, Pakistan. Thirty three eyes with subluxated lenses having zonular weakness less than 180 degrees were implanted modified CTR and IOL implant after lens matter aspiration. Main outcome measures were postoperative best-corrected visual acuity [BCVA], IOL centration, and complications. The age of 24 patients ranged from 2.5 to 38 years, mean 13.34 +/- 9.8 years. The follow up period was 20.87 +/- 2.40 months. The mean pre operative logMAR BCVA was 0.98 +/- 0.52 SD and the mean post operative logMAR BCVA was 0.38 +/- 0.32 SD [p value 0.000]. Intractable secondary glaucoma was seen in 01[03%] eye. One eye [03%] needed surgical anterior capsulotomy for anterior capsular phimosis. At the last follow-up visit, the modified CTR provided excellent centration and positioning in all cases. Modified CTR and primary IOL implantation in the capsular bag gives good visual outcome with no serious complications. However, it requires a highly experienced surgeon and sufficient patience for a relatively time-consuming procedure

Relationship between central corneal thickness [CCT] and intra ocular pressure

To determine relationship between central corneal thickness [CCT] and intra ocular pressure [IOP]. The study subject were recruited from Ophthalmology Outpatient Department, Dow University of Health Sciences and Civil Hospital Karachi, from January to July 2006 Patients above 40 years of age of either gender having no history of ocular trauma, disease or surgery, neither suffering from systemic disorder nor taking medicine for any disease were studied for CCT and lOP. Goldman applanation tonometry and pachymetry were performed in a single session, IOP was measured by Goldman Applanation Tonometer [GAT]. Pachymetry was performed with ultrasonic pachymeter. Regression analysis was conducted to determine relationship. Six hundred eyes of 300 patients [male 53%, female 47%], were analyzed. Average IOP was 14.83 mmHg. Average CCT was 54K microns. A significant association was found between CCT and IOP [r=0.63, p<0.001]. CCT was found to be correlated linearly with increased IOP values [p<0.000]. A positive relationship exists between CCT and IOP
