Indian survey on practice patterns of lacrimal & eyelid disorders (iSUPPLE): Report 3 - Cataract and nasolacrimal duct obstruction.

Aim: To assess the practice patterns pertaining to pre-cataract screening for nasolacrimal duct obstruction (NLDO) among oculoplastic surgeons in India. The survey was aimed at obtaining data on the current screening and treatment strategies for NLDO and the interval between lacrimal surgery and subsequent cataract surgery.

Methods: An online survey was sent to all members of Oculoplastic Association of India. All valid responses were tabulated and analyzed.

Results: Majority of the respondents (92%) felt that nasolacrimal duct patency should be checked prior to performing cataract surgery: 59.6% felt that checking for regurgitation on pressure over the lacrimal sac (ROPLAS) was sufficient and 32.6% preferred to perform lacrimal irrigation to check for NLD patency. Dacryocystorhinostomy (DCR) was the preferred surgery for NLDO thus detected. The preferred interval between a DCR and subsequent cataract surgery was 4 weeks (48.9%). A small minority (7.9%) of the respondents felt that pre-cataract screening for NLDO was not required. Also, a small but significant number (12.6%) felt that no treatment was required for NLDO in such patients and that to could go ahead with cataract surgery even in the presence of coexisting NLDO.

Conclusions: There is a general agreement on the need for pre-cataract screening for NLDO and a majority indicated that checking for ROPLAS was sufficient. Most surgeons prefer to perform a DCR in cases of NLDO and wait for 4 weeks before intraocular surgery. There is however, a lacuna in the literature on guidelines regarding the optimal interval between lacrimal surgery and subsequent intraocular surgery.
