Posterior polar cataract (PPC) remains a challenge for cataract surgeons because of its high association with complications such as posterior capsular rent and nucleus drop. PPC is associated with either a thin and fragile posterior capsule with the discoid opacity being adherent to it, or in up to 20% of cases, posterior capsule may be congenitally deficient.,
We hereby document a photo essay of a patient with posterior polar cataract with tell-tale signs of defective posterior capsule, which corresponds to type 3 variant of Daljit Singh's classification of PPC.
A 50-year-old healthy male presented with diminution of vision in both eyes since 1 year. Slit-lamp examination of both eyes showed distinctive discoid lens opacity situated at posterior pole of lens with concentric thickened rings around the central plaque opacity (bull's eye or onion peel appearance); dense white spots were also seen at the edge of the opacity (Daljit Singh sign) [Figure 1]a. Right eye also showed an elongated posterior capsule defect adjoining the central opacity which became prominent on pupillary retro illumination [Figure 1]b. The posterior segment shows yellowish shadow of the PPC embarking on the macula [Figure 2].

| Discussion|| |
The right eye PPC is a typical example of type 3 of Daljit Singh's classification of PPC where round or oval white opacity on posterior capsule has dense white spots (Daljit Singh sign) at the edge and is often associated with thin or absent posterior capsule. Singh also observed that there is a possibility of conversion of type 2 (posterior polar opacity with ringed appearance) to type 3 over a period of time. We managed this case with phacoemulsification with a 5 mm capsulorhexis placing a 3-piece IOL in the sulcus, ensuring that the anterior hyaloid face was not disturbed.,
Our report highlights a rare case of PPC and the importance of judicious preoperative assessment so that surgery can be planned by anticipating the complications and thereby minimizing the impact of complications.
