BACKGROUNDPosterior capsule opacification (PCO) is a frequently encountered complication of cataract surgery. However, Nd: YAG Laser capsulotomy is accepted as the treatment of PCO. Although Nd: YAG laser capsulotomy is noninvasive, it carries a risk of some complications. The purpose of this article is to have a bird's eye view of Nd: YAG Laser capsulotomy and its effects on the eye. MATERIALS AND METHODSThe present study comprised of a total number of 50 patients of Nd: YAG laser in the treatment of posterior capsular opacification after cataract surgery, who attended the Department of Ophthalmology, Rajah Muthiah Medical College and Hospital from 2015 to 2016. RESULTSA total of 50 patients were treated. Out of the 50 eyes that were studied, 25 were Right eyes and 25 were Left eyes. Most of the capsulotomies were done at the level of energy between 1.6 mJ to 2.4 mJ, consisted of 32 eyes. 10 capsulotomies were done at the level of 1.2 mJ to 1.5 mJ, while 8 capsulotomies were done at the level of 2.5 mJ to 3.1 mJ. The minimum amount of energy used was 1.2 mJ and maximum amount of energy used was 3.1 mJ. CONCLUSIONAlthough this procedure is safe, it is associated with complications like transient intraocular pressure rise, pitting of the intraocular lenses, mild iritis which are not vision threatening and they are transient. Therefore, this treatment modality is cost effective and safe. KEYWORDS Nd: YAG Laser, Posterior Capsule Opacification (PCO).HOW TO CITE THIS ARTICLE: Sridevi V.

“…Own studies found rates between 31% and 32% after 1‐2 years, and 77% and 49% after 3 years (Schriefl et al. ,) for the single‐piece hydrophilic M60 and Physiol Micro AY IOLs, respectively. These rates by far exceed the rates reported for standard hydrophobic acrylic IOLs fitting 2.2‐mm incisions.…”

PurposeTo evaluate the posterior capsule opacification (PCO) and YAG laser capsulotomy (YAG‐LCT) rates with a plate‐haptic acrylic micro‐incision intraocular lens (IOL) and the impact of primary posterior capsulorhexis.MethodsA total of 97 patients scheduled for immediate sequential bilateral cataract surgery underwent a randomized, prospective intraindividual comparison with the ZEISS Asphina 409MV plate‐haptic acrylic IOL with the eyes receiving an additional primary posterior capsulorhexis (PPCR) or not. YAG‐LCT and PCO rates were evaluated at 1 and 3 years. Three‐year PCO rates were calculated with a 3‐scenario method for eyes that underwent YAG‐LCT between 1 and 3 years.ResultsA total of 56 patients were seen at 1 year, and 57 at 3 years. For the eyes without and with PPCR, YAG‐LCT rates were 14.3% and 0% at 1 year, and 59.7% and 3.5% at 3 years, respectively. Opacification rates at 1 year were 0.55 ± 0.99 and 0.05 ± 0.21 for the central 2‐mm optic zone. A total of 42 patients completed both the 1‐ and 3‐year follow‐up. Three‐year opacification rates for the group without PPCR were 1.99 ± 2.20, 2.26 ± 2.66 and 3.66 ± 3.61 for the central 2‐mm zone and 2.57 ± 2.07, 3.13 ± 3.03 and 4.09 ± 3.34 for the 4.5‐mm zone for the best, extrapolated and worst‐case scenarios, respectively.ConclusionThe ZEISS Asphina 409MV plate‐haptic acrylic IOL exhibited unusually high YAG‐LCT and PCO rates with standard in‐the‐bag implantation. PPCR was safe and effective in preventing central opacification and the need for YAG laser treatment.

“…Ob MICS-IOLs zu höheren Nachstarraten führen, ist derzeit noch nicht abschließend geklärt. Schriefl und Kollegen konnten in einer Studie mit 60 Patienten und bilateraler simultaner MICS-Kataraktchirurgie zeigen (1 Auge mit hydrophober Y-60H, 3-stückig, Partnerauge mit hydrophiler MI60, 1-stückig implantiert), dass 4 Jahre nach Operation unabhängig vom Linsentyp bei mindestens 50% der Augen eine Nd-YAG-Kapsulotomie durchgeführt werden musste [19]. Augen mit der hydrophoben MICS-IOL wiesen eine noch höhere Nd-YAG-Kapsulotomierate von 77 % auf im Vergleich zu 50% bei den hydrophilen MICS-IOLs.…”

Development of an intraocular lens (IOL) as a drug delivery device has been pursued for many years and is a promising concept in modern cataract surgery. Common postoperative conditions such as posterior capsule opacification (PCO), intraocular inflammation or the rare but severe complications of cataract surgery like endophthalmitis are potential therapeutic targets for a drug-eluting IOL. There are three techniques of pharmacological IOL modification: Firstly, surface modification of the IOL ("coating"); secondly, IOL optic modification ("soaking") and lastly, loading the IOL haptics with a slow release system. The last option does not interfere with the IOL optics at all. Therefore, a broad spectrum of pharmacological agents needs to be assessed in preclinical and clinical studies to determine which agent/IOL combination is safe and efficient. For pharmacological PCO prophylaxis, erufosine-loaded IOLs are of great clinical interest. Heparin-coated IOLs might become clinically relevant for attenuation of intraocular inflammation after cataract surgery and cefuroxime-loaded IOLs for endophthalmitis prophylaxis.
