Purpose
To evaluate safety and efficacy of frequency doubled Nd- Yag laser photocoagulation of corneal vascularisation (NLPC)
Setting
- Prospective interventional study at a Tertiary Care Centre in South India , Karnataka
- Period: April 2021 to November 2022
Methods
- Prospective interventional study
- Place: Tertiary Care Eye centre South India, Karnataka
- Period: April 2021 to November 2022
- Inclusion criteria: 30 quiet eyes of 28 cases with superficial/ mid stromal/ deep stromal corneal vascularisation
- Intervention: Frequency doubled Nd-Yag laser photocoagulation, maximum two sessions.
- Response monitored: Resolution of vessels, complications & survival of subsequent corneal grafts was monitored upto 3 months.
Results
- 20 eyes (66.66%) had complete resolution of vascularisation with improved corneal clarity in 25% cases.
- Superficial(92.86%) and mid stromal vessels (75%) had a significant resolution, compared to deeper vessels (12.5%). 13 cases (43.33%) had ignorable flukes like minimal corneal burn (13.33%), iris holes (10%), anterior chamber bubbles (16.67%) & self resolving intrastromal bleed (6.67%).
- Of 12 eyes with subsequent keratoplasty, 1 (8.33%) had graft host junctional ectasia at lasered location.
Conclusions
NLPC is an effective non contact method to deal with superficial and mid-stromal corneal vascularization with no risk of perforation, infectious keratitis, LSCD & induced astigmatism, especially in cases where a large vessel arborizes within the stroma.
