Visual results and complications of temporal incision phacoemulsification performed with the non-dominant left hand by junior ophthalmologists.

AIMS: To assess the results of temporal incision phacoemulsification and aspiration performed with dominant and non-dominant hand of ophthalmology trainees. METHODS: Retrospective analysis were made of 203 surgeries with dominant hand and 207 with non-dominant by five trainees at two institutions. Trainees sat at the patient's head, manipulating instruments with the dominant right hand for the right eye, and the non-dominant left hand for the left eye. RESULTS: Vitreous loss occurred in 12 (5.9%) of 203 dominant operated eyes and seven (3.4%) of 207 non-dominant operated eyes. The rate of endothelial cell loss was 6.1% (9.8%) in dominant and 7.4% (12.4%) in non-dominant. Mean ultrasound time were 1.81 (0.70) minutes in dominant and 1.78 (0.78) minutes in non-dominant. One trainee showed statistically significant excesses in incidence of vitreous loss in dominant operated eyes (8.7%, p=0.0270), and one showed statistically significant prolongation of the operation in nondominant operated eyes (26.3 minutes, p=0.0315). In all other trainees, all parameters had no difference in both sides. CONCLUSIONS: Ophthalmology trainees could successfully learn the technique with both hands. The authors consider that the skill of the non-dominant hand may be knowledge based and that surgeons avoid mistakes by mental efforts.

[Pediatric cataract surgery with posterior capsulorrhexis and optic capture of the intraocular lens].

We evaluated the result of the pediatric cataract surgery with optic capture. The intraocular lens (IOL) optic is subluxated to the vitreous body side through the posterior continuous curvilinear capsulorrhexis (PCCC). Five eyes with congenital or developmental cataracts were treated with phacoemulsification and IOL implantation, and then PCCC and optic capture was done. Three of the cases were bilateral and one case was unilateral. All cases have remained in good condition without secondary fibrous membrane formation, which influences visual acuity, and transparency of the posterior capsule was maintained in the visual axis area. We found one case of anterior capsule contraction. Long-term follow up should be continued.
