The study of 30 patients was performed at Lahore General Hospital, and Institute Of Ophthalmology Mayo Hospital, Lahore from June 1989 to June 2003 for 14 years. Total number of eyes were 34 where 2 patients had both eyes. Age ranged from 12-65 years. Males were 11 and females were 19. all the patients had planned extracapsular cataract extraction with IOL implantation. Total follow up period ranged from 1-5 years and best corrected visual acuity in these patients after surgery was 6/12 to 6/6. Post operatively, eyes had vitreous membranes and glaucomatous reaction.

Purpose We conducted a double-masked, prospective study to evaluate the effect of 0.5% and 0.25% apraclonidine on postoperative intraocular pressure (IOP) in patients undergoing extracapsular cataract extraction (ECCE) with intraocular lens (IOL) implantation. Methods Fifty-four patients scheduled for ECCE were randomly divided into three groups of 18. The first group received one drop of 0.50% apraclonidine topically one hour before surgery and immediately after the end of the procedure. The second group received the same regimen but with 0.25% apraclonidine. The third group received artificial tears as the control group. IOP was measured 12 h preoperatively and 6 and 24 h postoperatively. All the measurements were made using the same Goldmann applanation tonometer by the same surgeon who did not know to which group the patient belonged. Results Preoperative mean IOP was 13.66 ± 2.76 mmHg in the first group, 14.27 ± 2.24 mmHg in the second and 14.5 ± 1.34 mmHg in the control group. The differences were not significant (p=0.398). Mean IOP at the early postoperative visit (6 h) was significantly lower in the first group (17.44 ± 4.95 mmHg) than the second (21.78 ± 7.19 mmHg) and the control group (24.55 ± 5.65 mmHg) (p<0.001). Mean postoperative IOP at 24 h was again significantly lower in the first group (14.33 ± 3.75 mmHg) than the second (17.11 ± 4.16 mmHg) and the control group (19.61 ± 3.20 mmHg) (p<0.001). Conclusions Our findings indicate that topical 0.5% apraclonidine controlled early postoperative intraocular hypertension after cataract extraction without any side effects, while the 0.25% drops were not effective.

Background/Aim. Cataract surgery has become one of the safest procedures in medicine thanks to advances in technology and surgical techniques. Although minimal, we still witness different complications. The aim of this study was to compare visual outcome and complication rate in different techniques of cataract surgery, ie in cataract surgeries with various corneal incision width. Methods. The study included 3,457 consecutive patients, ie 4,670 eyes that had undergone cataract surgery. The used surgical techniques were: extracapsular cataract extraction, phacoemulsification/ forceps IOL implantation, phacoemulsification/ injector IOL implantation, microincision cataract surgery (MICS). Patient follow up was 6 months. Patients were evaluated for: visual aquity, corneal astigmatism, cellular reaction in the anterior chamber, IOL position. Results. Uncorrected visual aquity 30 days postoperatively was ? 0.5 in 30% of the eyes - ECCE; 54.7% of the eyes - phacoemulsification/forceps IOL implantation; 63.0% of the eyes - phacoemulsification/injector IOL implantation; 5/8 of the eyes - MICS. Endophthalmitis was detected in 0.15% of the eyes - ECCE and 0.1% of the eyes - phacoemulsification/forceps IOL implantation. In eyes with phacoemulsification/injector IOL implantation or microincision cataract surgery (MICS) there were no cases of endophthalmitis. After a 6-month period intraocular lens were dislocated in 7.2% of the eyes - ECCE, and 0.6% of the eyes - phacoemulsification/PMMA IOL. There was no IOL dislocation in other surgical techniques. Conclusion. Shorter corneal incision implies less complications, less operative trauma, faster visual rehabilitation and better visual outcome.

Purpose To evaluate the effectiveness of phenylephrine 2.5% and flurbiprofen 0.03% combined in inducing and maintaining mydriasis during extracapsular cataract extraction (ECCE). Methods One hundred patients undergoing ECCE + intraocular lens (IOL) implantation were randomly divided into four groups. The first group was given phenylphrine 10%, the second group phenylephrine 10% + flurbiprofen, the third group phenylephrine 2.5% and fourth group phenylephrine 2.5% + flurbiprofen. Cyclopentolate 1% was used in all patients. Phenylephrine and cyclopentolate were instilled preoperatively four times during 1 hour and flurbiprofen was given four times the day before surgery and twice with an hour's interval before operation. Pre-operative and post-cortex aspiration horizontal pupil diameters were measured with callipers viewed through the operating microscope. Results Pupil diameters in pre-operative and post-cortex aspiration were no different in the 2.5% and 10% phenylephrine groups (p>0.05). Both diameters were larger and pupillary constriction was smaller in the flurbiprofen groups (p<0.05). Conclusions 2.5% phenylephrine was as effective as 10% phenylephrine, with and without flurbiprofen, in inducing and maintaining pupil dilatation during ECCE surgery.

Iol Fixation

A prospective study was conducted on 90 eyes undergoing extracapsular cataract extraction and posterior chamber IOL implantation. Postoperative IOL decentration was evaluated with respect to the loop material, either polypropylene (prolene) or polymethylmethacrylate (PMMA), and the IOL fixation technique, either in the capsular sac (in-the-bag) after capsulorhexis, or in the ciliary sulcus after “can-opener” capsulotomy. More decentration was observed with IOL having polypropylene loops than with those having PMMA loops (0.80 ± 0.735 mm versus 0.373 ± 0.299 mm). IOL implanted in the bag showed greater decentration than those implanted in the sulcus, but the difference was not significant. Our findings confirm the recommendation to use an IOL with PMMA loops when placing the implant in the capsular sac.
