Background: During combined phacovitrectomy, it is common practice to suture the main corneal incision to prevent intraoperative and postoperative wound leak. However, it may be possible to avoid suturing using a self-sealing corneal incision technique as in standard cataract surgery.

Objectives: To evaluate the clinical outcome, safety, and complications of combined phacovitrectomy without preventive suturing.

Methods: This retrospective case series study included consecutive patients who underwent combined phacovitrectomy between January 2018 and June 2019 for mixed indications. Surgeries were performed at a tertiary university hospital. All surgeries were performed by the same two retinal surgeons. Cataract surgery was performed first, followed by insertion of trocars and vitrectomy. Corneal sutures were not planned but were used at the discretion of the surgeon.

Results: The cohort included 106 eyes of 102 patients. Suturing of the main corneal incision was deemed necessary in five cases (5%) because of a main incision leak or anterior chamber shallowing during trocar insertion. No other complications related to the absence of prophylactic corneal sutures were encountered during surgery or follow-up.

Conclusions: Preventive corneal suturing may not be necessary in combined phacovitrectomy surgery and can be used in the few cases in which it is indicated during surgery.

Background: The prevalence and incidence of blindness in Israel appear to be comparable to other western countries. Comparisons are difficult because of different definitions of blindness, and the uniqueness of the Israeli registry for the blind.

Objective: To characterize the population who were registered as Blind in Israel in the years 1998–2003 and estimate the prevalence and incidence of blindness by age and causes of blindness.

Methods: A retrospective review of the annual report of the National Registry for the Blind in Israel between 1998 and 2003 identified 21,585 blind persons who received a certificate for blindness. Blind persons are identified by ophthalmologists throughout Israel and referred to the Registry of the Blind if they have a visual acuity of 3/60 or worse, or a visual field loss of < 20 degrees in their better eye. This report includes prevalence data on 21,585 persons enrolled in this review still alive and living in Israel in 2003. We estimated the prevalence rate of blindness nationwide and the incidence rate for each cause of blindness for every year.

Results: The main leading causes of blindness in Israel in 1998 were (in percent of the total number of newly registered patients): age-related macular degeneration (20.1%), glaucoma (13.8%), myopic maculopathy (12%), cataract (10.4%), diabetic retinopathy and maculopathy (10.1%), and optic atrophy (7.9%), and in 2003, 28%, 11.8%, 7.4%, 6.5%, 14.4% and 6.5% respectively.

Conclusions: The results indicate that the incidence of age-related macular degeneration, diabetic retinopathy and maculopathy in Israel is increasing, while that of glaucoma, myopic maculopthy, optic atrophy and cataract is decreasing.

Background: Corneal erosions, a common and very painful ailment, are traditionally treated with pressure patches and antibiotic ointment but the healing is slow.

Objectives: To report our experience with the use of therapeutic contact lenses for the primary treatment of traumatic corneal erosions.

Methods: During the last 5 years in a single community clinic 65 consecutive patients with traumatic corneal erosions were treated with a corneal contact lens and antibiotic drops as a routine measure. The charts were reviewed for outcome, side effects and complications.

Results: Healing of the corneal erosions occurred within 1 to 3 days in all patients, with minimal or no pain. No corneal infection occurred. One patient had a recurrence that was successfully treated by lens placement.

Conclusions: The therapeutic contact lens with antibiotic drops is a safe and effective method to treat traumatic corneal erosions, and patients can immediately resume their regular activities.

Background: The time to recurrence after surgical removal of primary pterygium (pterygium) and the association between the rate of recurrence and the postoperative interval remain unclear.

Objective: To determine the amount of follow-up time needed to identify recurrence in patients after surgical removal of pterygium.

Methods: We rviewed the files of 143 patients (143 eyes) with recurrent pterygium to determine the interval from surgery to recurrence.

Results: Almost all (91.6%) of the recurrences appeared by 360 days after surgery.

Conclusions: One year is the optimal follow-up time to identify recurrence of pterygium.

Background: Previous work has suggested an association between increasing size of pterygium and increasing degrees of induced corneal astigmatism.

Objectives: To assess the quantitative relation between pterygium size and induced corneal astigmatism using a computerized corneal analysis system (TMS II) and slit-lamp beam evaluation of pterygium size, and to conclude whether corneal astigmatism is an early indication for surgical intervention.

Methods: We evaluated 94 eyes of 94 patients with unilateral primary pterygium of different sizes, using TMS II and slit-lamp beam measurements of the size of the pterygium (in millimeters) from the limbus to assess parameters of pterygium size with induced corneal astigmatism. Best corrected visual Snellen acuity was performed.

Results: Primary pterygium induced with-the-rule astigmatism. Pterygium extending 16% of the corneal radius or 1.1 mm or less from the limbus produced increasing degrees of induced astigmatism of more than 1.0 diopter. Significant astigmatism was found in 16.16% of 24 eyes with pterygium of 0.2 up to 1.0 mm in size, in 45.45% of 22 eyes with pterygium of 1.1 up to 3.0 mm in size (P≤0.0004), and in 100% of 3 eyes with pterygium of 5.1 up to 6.7 mm in size (P=0.0005). We found that visual acuity was decreased when topographic astigmatism was increased.

Conclusions: When primary pterygium reaches more than 1.0 mm in size from the limbus it induces with-the-rule significant astigmatism (≥1.0 diopter). This significant astigmatism tends to increase with the increasing size of the lesion. Topographic astigmatism tends to be improved by successful removal of the pterygium. These findings suggest that early surgical intervention in the pterygium may be indicated when the lesion is more than 1.0 mm in size from the limbus.
