100 patients undergoing phacoemulsification were randomly allocated to superior or temporal limbal incision. Temporal incision was associated with significantly less surgically induced astigmatism than superior limbal incision
286 eyes of 170 patients were studied. Each patient underwent complete ocular examination and refraction. Visual outcome after refraction was comparatively worse in keratoconus patients associated with VKC due to photophobia, active conjunctivitis, scaring and vascularization.
To assess the efficacy and safety of excimer laser photorefractive keratectomy for myopia 44 eyes within range of -3.75 to 6.00 diopters sphere underwent PRK. At one month, three months, and six months after PRK, 45.45%, 63.63%, and 74.31% eyes respectively achieved 6/6 visual acuity without glasses. PRK
appeared to be an effective and safe procedure with good predictability for the correction of moderate myopia.
A one year old female child with bilateral congenital cataract underwent simultaneous cataract surgery in a single session in order to reduce the risk of repeated general anesthesia. No per operative complication occurred and satisfactory visual outcome was achieved
Intubation in experienced hands is a successful procedure for treating congenital nasolacrimal duct obstruction mostly after failed probing. 37 eyes were treated with lacrimal intubation using olive tip silicon tube. Success of intubation was seen in 32 out of 37 intubated eyes (86.48%). Tube removal in office is cost effective and safe.
Comparison of surgically induced astigmatism in phacoemulsification with 5.5 mm superior vs. temporal incision
Purpose: To compare the effect of superior versus temporal limbal incision on surgically induced astigmatism (SIA) in phacoemulsification with 5.5 mm rigid intraocular lens (IOL) Duration and Setting: Department of Ophthalmology Fauji Foundation Hospital, Rawalpindi, from January 2006 to December 2006. Patients and Methods: A total of 100 patients undergoing phacoemulsification with posterior chamber (PC) IOL comprise the study. They were randomly allocated to two groups i.e. Group 1 (superior limbal incision) and Group 2 (temporal limbal incision). 5.5 mm limbal incisions were given in superior and temporal meridians. All surgeries were performed by the same surgeon. All patients had autokeratometry preoperatively and post operatively (4 weeks and 8 weeks). Surgically induced astigmatism was measured by using vector subtraction method ignoring the axis. Statistical analysis was done by using paired sample T test. Results:After 8 weeks Group One had 1.41 diopters of SIA and patients of Group Two had mean SIA of 1.03 D. The difference was statistically significant with p value of 0.002.
Comparison of Visual Outcome after Refraction in Keratoconus associated with and without VKC
Kanwal Batool Dip.Optom. Amtul Aziz DOMS
Purpose: To compare the visual outcome after refraction in mild, moderate and severe keratoconus associated with and without vernal keratoconjunctivitis (VKC). Design: Retrospective analysis of patients with keratoconus. Participants: Patients treated at refraction unit of Cornea Clinic of Al-Shifa Trust Eye Hospital Rawalpindi Methods: 286 eyes of 170 patients were studied. Each patient underwent complete ocular examination and corneal topography by an ophthalmologist and visual acuity, keratometry and refraction by an optometrist Results: Majority of patients (94.11%) presented between 8-29 years of age. Mean age was 17.41 years; 5.85% patients presented between 30-45 years of age. 70.58% were male and 29.41% were female.. Out of 286 eyes with keratoconus, 16 eyes had mild keratoconus (K- readings < 48D), 51 eyes had moderate keratoconus (K- readings between 48-54D) and 219 eyes had severe keratoconus (K-readings > 54D). The VKC was associated with 44.75% of patients. Visual outcome was 6/9 or better in 27.69 % (36 eyes) without association of VKC and 8.59 % (11 eyes) in association with VKC
Excimer Laser Photorefractive Keratectomy for 3.75 to 6.00 Diopters of Myopia- Six Months Follow Up
M Abdul Moqeet, FCPS
Purpose: To assess the efficacy and safety of excimer laser photorefractive keratectomy for myopia in Pakistani population.
Design: Prospective interventional case series Participants: This study group included 44 eyes within range of -3.75 to 6.00 diopters sphere (DS). Range of the astigmatism was 0.50 to 1.50 diopters cylinder (DC), with an average of 0.93. Nine eyes (20.45%) were lost to follow up after three months. Therefore 35 eyes (79.45%) were examined at final visit scheduled at six months postoperatively. Methods: All patients presenting at the cornea clinic with moderate myopia and eligible and willing for PRK underwent laser surgery by the same surgeon. The patients were examined at one, three and six months for outcome measures which included visual acuity, incidence of complications, and patient satisfaction. Results: At one month, three months, and six months after PRK 45.45%, 63.63%, and 74.31% eyes respectively achieved 6/6 visual acuity without glasses. It was found that 23 eyes (52.27%), 24 eyes (54.54%) and 17 eyes (48.57%) had hypermetropia of +1.00 diopters spherical equivalent (DSE) after one month, three months and six months respectively. None of the eyes had astigmatism more than +1.0 diopters, whereas 02 eyes (05.71%) had -1.0 diopter astigmatism at the end of six months. After six months, eleven eyes (31.33%) still had postoperative corneal haze varying between grades 1 to 3. No vision threatening complication occurred.
Simultaneous Bilateral Cataract Surgery in children – A Case Report
Samina Jahangir, FCPS, Mahmood Ali, MBBS
Purpose: Feasibility of simultaneous bilateral cataract surgery (SBSC) in children with congenital cataract Design of study: A case report. Participants: A one year old female child with bilateral congenital cataract who was brought to outpatient department of Jinnah Hospital Lahore with the complaint of visual inattention. Her general health did not permit repeated general anesthesia and so simultaneous cataract surgery in a single session was planned. No per operative complication occurred and satisfactory visual outcome was achieved.

Saemah Nuzhat Zafar FRCS, Ayesha Khan FRCS, Clinical Fellow in Pediatric Ophthalmology,Nadia Azad FCPS
Purpose: To report results of lacrimal intubation for management of congenital nasolacrimal duct obstruction. Design: Prospective interventional case series. Participants and Methods: Twenty nine consecutive patients (37 eyes) with nasolacrimal duct obstruction requiring lacrimal intubation presenting at the Paediatric Ophthalmology Department of Al-Shifa Eye Hospital, were included in the study with informed consent. After detailed history and ophthalmic examination 37 eyes were treated with lacrimal intubation using olive tip silicon tube in the operating room. Patients were followed up at 1 week, 6 weeks and thereafter at varied intervals according to symptoms or complications such as lateral displacement of the tube. Tube was removed after an average of 6.8 months as an office procedure in most of the cases. Complications of the procedure were noted. Success of the procedure, defined as no watering, mucous discharge or increased tear meniscus seen after intubation was noted. Results: Success of intubation was seen in 32 out of 37 intubated eyes (86.48%). Further success was seen in 2 eyes of 2 patients after removal of the tubing. Three eyes required dacryocystorhinostomy surgery for persisting symptoms with regurgitation of discharge. Operative complications of lacrimal intubation included bleeding from nasal mucosa, difficult retrieval of the tube from the nose due to anatomical reasons and slipping off of the tube from its metal probe, punctal tear, unplanned silicone tubing removal, obstruction encountered during the procedure and lateral displacement of the tube.
