ABSTRACT
PURPOSE:
To determine the incidence, risk factors and clinical outcomes in patients with nucleus drop (ND) following phacoemulsification surgery at a tertiary care ophthalmic institute.METHODS:
Medical records of patients with ND during phacoemulsification between January'2019 and December'2022 were reviewed retrospectively. Incidence of ND was calculated overall, and according to surgical expertise levels and surgical steps. Associated pre- and intra-operative risk factors were assessed. Clinical outcome parameters [best-corrected visual acuity (BCVA) and intraocular pressure (IOP)] were compared with respect to timing of PPV (immediate vs early vs delayed), location (sulcus vs scleral fixated-IOL) and timing of IOL placement (primary vs secondary).RESULTS:
Among 93,760 phacoemulsifications, ND was noted in 130 patients (0.1%). Significant direct and associated pre-operative risk factors were advanced cataract, glaucoma, posterior polar cataract, and diabetes mellitus. Junior medical consultants had 40 ND (mostly in non-complex cases), whereas senior medical consultants had 90 ND (mostly in complex cases). ND most frequently occurred during emulsification of nuclear fragments. Sulcus placement of IOL during primary surgery yielded significantly better visual outcome compared to secondary procedures, although timing of PPV had insignificant effect. 77.1% had BCVA of 6/12 or better at final follow-up. Timing of IOL implantation, PPV, and type of IOL did not have any significant effect on IOP.CONCLUSIONS:
Though the incidence of ND is low, it is a dreaded complication. Accurate pre-operative evaluation, risk stratification, distribution of cases among surgeons based on their surgical expertise, and immediate or early management of ND yields better anatomical and functional outcomes.Key words
