Purpose • The aims of this study wereto report outcomes of surgery for posterior polar cataract using the OZil torsional handpiece.
Method-I • Medical records of 26 eyes of 21 consecutive patients with posterior polar cataract who had cataract surgery using the OZil torsional handpiece were evaluated • The cataract surgeries were performed by the same surgeon (AP) • All surgeries were carried out under peribulbar anaesthesia
Method-II • Continuous curvilinear capsulorhexis was performed under an ophthalmic viscosurgical device • Hydrodissection was avoided in order to prevent posterior capsule rupture • All patients underwent hydrodelineation • For soft nucleus, the chip and flip technique was used. The parameter used were 100 mmHg and 20% torsional amplitude
Method-III • For harder nucleus (grade II-III), the stop and chop technique was used. The parameters used for trenching were 50-60 mm Hg vacuum and 80%-90% torsional amplitude. Emulsification was done at the 60%-70% torsional amplitude at an increased vacuum pressure of 100 mmHg. • Throughout the procedure the aspiration flow rate was 16-18 ml/min at the bottle height of 50-60 cm
Method-IV • In all cases the epinucleus was aspirated and pulled towards the centre without crossing the central area • All cortex had been brought to the centre it was aspirated together with the central area • Usually, the plaque came out with the aspiration, but in some there was central posterior capsule rupture
Results • Of the 26 eyes, 24 (92.3%) had small to medium posterior polar opacity. Two eyes had large opacity. • Posterior capsule rupture occurred in 4 (15.3%) eyes. The mean visual acuity improved significantly after surgery (p<0.001). • The postoperative visual acuity was worse than 20/20 in 5 eyes. The cause of the low acuity was amblyopia.
Conclusion • Posterior polar cataract can be safely extracted using the OZil torsional handpiece. • Phacoemulsification using the OZil torsional handpiece leads to good visual outcome.
