विध्येत्सुजातं निष्प्रेक्ष्यं लिङ्गनाशं कफोद्भवम् । आवर्तक्यादिभिः षड्भिर्विवर्जितमुपद्रवैः ॥ १ ॥
Linganasha (blindness due to opacity of the lens / cataract) which is of Kapha origin, which has developed fully (ripened), becomes opaque, which has caused complete loss of vision, which is not having six complications such as the Avartaki etc. should be punctured (couching done).
सोऽसञ्जातो हि विषमो दधिमस्तुनिभस्तनुः । शलाकयाऽवकृष्टोऽपि पुनरूर्ध्वं प्रपद्यते ॥२॥
It (Linganasha), when not fully formed, is uneven, resemble the water of curds (in colour), thin; when pressed hard by a metal rod it again moves upwards, causes severe pain and hinders vision;
again (even after puncturing) gets filled quickly by ingestion of foods which increase Kapha and even others (Vata and Pitta), becomes associated with complications which persists for long.
श्लैष्मिको लिङ्गनाशो हि सितत्वाच्छ्लेष्मणः सितः । तस्यान्यदोषाभिभवाद्भवत्यानीलता गदः ॥ ४ ॥
Linganasha born from Kapha is white. Because of the white color, it is caused due to Kapha. When it is dominated by other doshas, it attains bluishness.
तत्रावर्तचला दृष्टिरावर्तक्यरुणासिता । शर्करार्कपयोलेशनिचितेव घनाति च ॥ ५ ॥
Avartaki is that, in which the vision (less) is unsteady like a whirl and slightly red or black in color. Sharkara is that in which, the vision (lens) appears as though smeared with milky sap of Calotropis gigantea and is thick / hard.
