The goal of this interventional comparative study is to assess the efficacy and safety of a novel regimen of preservative-free unit-dose topical anesthetics for controlling early postoperative pain following single-step transepithelial PRK surgery.
The main research questions to answer are:
Question 1: Are topical anesthetics effective in reducing post-PRK pain?
Question 2: Are short-term topical anesthetics toxic to the cornea?
Question 3: How to prevent abuse of topical anesthetics by patients at home?
Participants were planned to undergo a bilateral single-step transepithelial PRK surgery to correct their refractive errors and received a standard post-PRK treatment regimen for both eyes. Additionally, one eye was offered a preservative-free topical anesthetic as an experimental group and the other eye was offered a preservative-free artificial tear as a control group.

Hemodynamic Response Of Premature Brain To Pain During Retinopathy Of Prematurity Screening: A Randomized Controlled Trial

Study of cerebral hemodynamic changes in preterm infant and the effect of topical anesthetic eye drops ( benoxinate hydrochloride 0.4% ) on PIPP score and cerebral hemodynamic changes during fundus examination in neonates with gestational age ≤ 34 weeks or birth weight ≤ 2.000 Kg regardless their gestational age , after postnatal day 28.

Effect of Benoxinate Hydrochloride Eye Drops on The Premature Infant Pain Profile Score During Retinopathy of Prematurity Screening

Aims: To evaluate the effects of topical Benoxinate HCL eye drops on the Premature Infant Pain Profile (PIPP) scores in infants undergoing Retinopathy of Prematurity (ROP) screening.
Methods: A randomized prospective double-masked cross-over trial was conducted on preterm infants screened for ROP at least twice. Dilated fundus examination was done in Group A infants using the tear substitute eye drops and the second using the Benoxinate HCL drops and the reversed order of drops for Group B. Video recording of the pulse oximeter monitor, the face and the body of the infant were analyzed by a single neonatology consultant for Premature Infant Pain Profile (PIPP) scoring 1 minute before, during the examination of the first eye, 1 minute and 5 minutes after the conclusion of the examination of the second eye. The sound of the ophthalmologist on the video recordings indicating the time of the lid speculum insertion, the shining of the indirect ophthalmoscope light without indentation and the scleral indentation would aid in assessing the differences of the PIPP indicators during each step of the examination.

Optimizing injection accuracy for Baxter’s nerve entrapment: an ultrasonography-guided approach based on anatomical surface landmarks

Article

Author: Nam, Yong-Seok ; Kim, In-Beom ; Lee, Hyung-Jin ; Kim, Sang-Hyun ; Choi, Jung-woo ; Kim, Jun-Ho ; Shin, Mi Young

INTRODUCTIONThe clinical feasibility and applicability of surface landmarks for Baxter nerve entrapment to proximal and distal sites is unclear. This study provides anatomical guidelines for optimal transducer placement using two specific landmarks, the most inferior tip of the medial malleolus (A) and the most protruding posterior tip of the calcaneus (B), to enhance the diagnostic and therapeutic injection efficacy for proximal and distal entrapment sites.MATERIALS AND METHODSEighty-six feet from 45 fresh cadavers (25 male and 20 female) were dissected to determine Baxter's nerve (BN) localization. With A and B as key landmarks, distances (OB, OBN, BBN, and BNx) were measured to accurately localize the nerve. The OB distance was divided into four equal-length quadrants or zones. Twenty feet from 10 fresh cadavers (5 males and 5 females) underwent ultrasonography-guided injection using in-plane and out-of-plane techniques. Two practitioners marked the landmarks to ensure reproducibility and an experienced anesthesiologist administered the injections. The spread of the injected dye was assessed, and statistical analyses were conducted.RESULTSAverage OB, OBN, BBN, and BNx distances were 50.55 ± 5.83 mm, 7.19 ± 5.85 mm, 43.77 ± 5.31 mm, and 12.13 ± 5.75 mm, respectively. Significant sex-related differences (O to B; B to BN) and notable disparities between the distances on the right and left sides (O to BN; BN to X-axis) were observed. Most of the BN (81.4%) was located in zone 1, representing 25% of the OB length. For entrapment site 1, the in-plane technique achieved a 100% success rate whereas the out-of-plane method achieved an 80% success rate. For entrapment site 2, the out-of-plane approach (90% success) outperformed the in-plane approach (20% success).CONCLUSIONUsing two specific landmarks provides reliable guidelines for optimal transducer placement during injections targeting compressive neuropathy at proximal and distal entrapment sites.

Spring and parachute approach for piroxicam dissolution; its phenomenological model on the thermodynamics of irreversible processes

Article

Author: Moritake, Kota ; Kataoka, Hikaru ; Tsuchida, Tomohiro ; Tsunoda, Chihiro ; Goto, Satoru ; Fujita, Momoko

Even though the spring and parachute approach for poorly water-soluble drug candidates effectively improves their dissolution curves with eutectic mixtures, deep eutectic solvents, solid dispersion polymers, and solid solutions, we cannot consider that its enabling factor in these pharmaceutical modifications was enough to be clarified. Based on our previous study that oxybuprocaine acts as a role of parachute generator for piroxicam, the present study explored a small-molecule parachute generator and found that propranolol, a β-adrenergic-blocking drug, has a parachute effect on the supersaturated state of piroxicam. In addition, changing the concentration of tetracaine and dibucaine to 10 mM and 2.5 mM also showed a parachute effect. These parachute generators control piroxicam's dissolved state kinetically by making the supersaturated state of piroxicam a steady state. However, as the piroxicam anhydrous crystals diminished and the piroxicam monohydrate crystals grew due to Ostwald ripening, it led to attenuating the supersaturated state. This finding advances the elucidation of the mechanism of the parachute effect of polymers.

Comparing the intraocular pressure values obtained with a rebound tonometer (TONOVET Plus) and an indentation tonometer (IOPvet) in dogs with and without ocular disease

Article

Author: Michaud, Bertrand ; Lesne, Fabien

AbstractBackgroundThis study aimed to compare the intraocular pressure (IOP) values obtained from two groups of dogs using the IOPvet indentation tonometer to those obtained from the same dogs using an established rebound tonometer (TONOVET Plus).MethodsTonometry was performed on 36 dogs with ocular diseases (70 eyes; group A) and 25 healthy dogs (49 eyes; group B). First, the TONOVET Plus rebound tonometer was used. Then, one drop of oxybuprocaine hydrochloride was applied to each eye, and 1 minute later, the IOP was estimated using the IOPvet.ResultsThe IOPvet was safe, well tolerated and easy to use. The instrument had a high specificity (98.5%) for identifying IOPs of 20 mmHg or less. A lack of sensitivity (67.9%) was noted when evaluating eyes with an IOP between 20 and 30 mmHg. The sensitivity (33.3%) for identifying canine eyes with an IOP of greater than 30 mmHg (n = 24) was low.LimitationsThis study lacks manometric work, which would be hard to justify with client‐owned dogs. Quantitative numerical data were compared with qualitative values and the same investigator obtained readings using both tonometers without being masked.ConclusionsThe IOPvet is highly sensitive for assessing normal IOPs, but underestimation of higher IOPs can lead to poor diagnostics. Digital tonometers remain the best way to assess IOP in veterinary clinics.
